When images lag, visitors leave, Core Web Vitals suffer, and search rankings drop. Bandwidth Saver serves the images on your pages from your own [img.pro](https://img.pro) App, through img.pro’s image CDN. Each image is copied the first time a page shows it, so your App holds the images visitors actually see and nothing else. Your server stops sending image bytes to every visitor, and pages load faster. **Your files, your account.** Images are uploaded straight from your server’s disk, so it works on staging sites, password-protected sites and sites that are not public yet. Everything lives in an img.pro App you own, and you can delete it from the plugin at any time. Copies on img.pro can be loaded by anyone who has their address. #### How It Works 1. Create an App on img.pro (the Free plan works) and copy an API key with Read and Write permission. 2. Paste the key in **Settings > Bandwidth Saver**. 3. The first time a page shows an image, the plugin copies it to your App in the background. Until the copy is ready, the image loads from your server. 4. From then on, pages load the image from img.pro. Images no page shows are not copied unless you copy them from the Media Library, so until then they use none of your App’s images. WordPress stays in charge of your images. Each size WordPress creates (the full image and each thumbnail size) is copied unchanged, when a page first uses it or when you copy the image, and served at the same dimensions, so your theme, srcset and image editor keep working exactly as before. #### Why Use an Image CDN? * **Faster page loads.** Images come from img.pro’s global network instead of your web host. * **Better Core Web Vitals.** Faster image delivery helps LCP (Largest Contentful Paint). * **Less load on your server.** Your host no longer serves image traffic for copied images. * **Safe by design.** If img.pro cannot deliver an image, the browser loads it from your server instead. #### Supported Image Formats JPG, PNG, GIF, WebP, AVIF and HEIC, up to 20 MB per file. SVG, BMP, ICO, TIFF, animated PNGs and files over 20 MB stay on your server and keep working as normal. #### Pricing The plugin is free. Storage and delivery are provided by your img.pro App, and img. pro plans count stored images, not bandwidth: * **Free**: up to 5,000 images per App, at no cost. * **Pro**: up to 50,000 images per App, for $20 a month. * **Unlimited**: no limit, for $100 a month. See [img.pro pricing](https://img.pro/product/pricing) for the current plans. Each copied file counts as one image. WordPress saves every photo in several sizes, often 4 to 8. When a page shows a photo, every size its srcset offers the browser is copied, so a photo usually uses 4 to 6 images, and a small one fewer. Images no page shows use none. #### The Media Library * An **img.pro** column in list view, and an img.pro line in each image’s details, show whether an image is copied, queued, not copied yet, or stays on your server, and why a copy failed. * **Copy to img.pro** copies an image ahead of time, from its row, its details or its edit screen. To copy several, select them in list view and choose Copy to img.pro from Bulk actions. * **Copy img.pro URL** copies the address of an image’s img.pro copy, for images used where Bandwidth Saver does not change URLs, such as theme CSS. #### What Gets Served From img.pro * Images from your media library that your pages show, in every size they use * Images inserted in posts, pages and widgets * Featured images and images your theme or plugins output with `wp_get_attachment_image()`, such as WooCommerce product images, including srcset * Images your posts load from other websites, such as an earlier domain of your site or an image inserted from a URL. img.pro copies each one from its address the first time a page shows it. You can turn this off in **Settings > Bandwidth Saver**. Theme files and other files on your own server that are not in the media library are left alone. #### Works With Your Theme and Plugins * **Block editor and classic editor** * **WooCommerce** product images and gallery thumbnails * **Page builders** that output standard media library image URLs * **Lazy loading**, native and plugin-based * **Responsive images** with full srcset support * **Caching plugins** such as WP Rocket, LiteSpeed Cache, W3 Total Cache and WP Super Cache #### Need Video or Audio? This plugin is for images only. Video, audio and other files keep loading from your server. ### Privacy The plugin does not add cookies, tracking scripts or analytics to your site. When you connect an img.pro API key, the plugin uploads the image files your pages show, and those you copy from the Media Library, to your img.pro App. Images your pages load from other websites are copied by img.pro from their address, so those websites receive a request from img.pro. Each upload includes your site’s address, the attachment ID, the image size name, its path in the uploads folder, its file size and a fingerprint of its contents (an MD5 hash), so the plugin can find and manage its images later. Your API key is stored encrypted in your WordPress database. Images on img.pro are public: anyone who has an image’s img.pro address can load it, without a key. Copying from a private, password-protected or staging site makes those images reachable at their img.pro address. Visitors’ browsers load copied images from img.pro, so img.pro receives the usual request data a browser sends to any website, such as IP address and user agent. ### External Services This plugin connects to **img.pro**, an image hosting and CDN service, to store your images and deliver them to visitors. Nothing is sent until you paste an img. pro API key on the settings page. * **img.pro API** (`api.img.pro`): used to check your API key and plan, upload images, list the images this site uploaded and delete them. Data sent: your API key, image files from your media library, and the site address, attachment ID, size name, file path, file size and MD5 hash of each image, plus the address of each image from another website that a page shows (img.pro then fetches it from that address). Requests are made when you connect, when a page shows an image that is not copied yet (it is uploaded in the background), when you copy images from the Media Library, when images are deleted or replaced, during the background sync, and when you view the settings page or, while copying is paused, the Media Library. * **img.pro CDN** (`src.img.pro`): visitors’ browsers load copied images from this domain. Service provider: img.pro.

Install and activate the plugin. 2. Sign in at [img.pro/apps](https://img.pro/apps) and create an App. The Free plan works. 3. In the App, open **API Keys** and choose **New key**. Keep **Read** and **Write** ticked and, if it asks for **Data access**, keep **App storage only**. img.pro shows the key once, so copy it. 4. In WordPress, go to **Settings > Bandwidth Saver**, paste the key and click **Connect**. From then on, each image is copied the first time a page shows it, and switches to img.pro as soon as its copy is ready. The settings page shows how many files are copied, queued and not copied yet. On a multisite network, each site connects its own key from its own **Settings > Bandwidth Saver** page. ## FAQ ### Do I need an img.pro account? Yes. Bandwidth Saver 2.0 serves images from your own img.pro App, so you need an img.pro account and an API key. The Free plan is enough to get started. ### Will this change the files on my server? No. Your original files stay on your server and your database keeps its normal URLs. The plugin only uploads copies to img.pro and changes image URLs on your public pages. Deactivate it and every image loads from your server again. ### How many img.pro images will my site use? Only files your pages show are copied, and each copied file counts as one image. WordPress saves a photo in several sizes, often 4 to 8, and a page that shows it offers most of them to the browser in its srcset, so a photo usually uses 4 to 6 images. Images no page shows, such as old uploads nothing links to, use none. Images your posts load from other websites count too, one image each. The settings page shows how many files are copied and how many images your App stores. ### Can I copy an image before a page shows it? Yes. In the Media Library, choose **Copy to img.pro** under the image in list view, or in its details. To copy several, select them in list view and choose **Copy to img.pro** from Bulk actions. Every size of the image is copied. Bandwidth Saver changes image URLs in post content, widgets, featured images and images output with `wp_get_attachment_image()`. Images whose URL a theme or plugin reads directly, such as background images in theme CSS or a social sharing image, keep their server address; copy them and use **Copy img.pro URL** in their details. ### What happens when my img.pro App reaches its plan’s limit? Copying pauses. Images that were already copied keep loading from img.pro, and new ones keep loading from their original address. The App’s owner can upgrade it in Billing on img.pro, or you can delete media you no longer use in WordPress, which deletes its copies too. Copying starts again on its own once the App has room, or you can click **Try again now** on the settings page. Deleting this site’s images in the img.pro App itself does not make room for long: WordPress still uses those files, so Bandwidth Saver notices the missing copies ( it checks up to 200 of its copies every hour, oldest first) and copies the files again. Until then, pages load those images from your server. ### Does img.pro resize or convert my images? img.pro does not resize them. WordPress keeps creating every size, and img.pro serves each one at the same dimensions, as a high-quality copy in the same format (lossless for PNG). It removes hidden photo metadata, such as camera details and GPS location, and converts colors to sRGB. HEIC files are served as JPEG. Animated PNGs stay on your server, because img.pro shows PNGs as still images. The files you uploaded are stored unchanged. ### Can several sites use the same img.pro App? Yes. Each image is labelled with the site it came from, and the plugin only lists or deletes images that carry its own site’s label. All sites share the App’s image limit. ### I copied my site to a staging site. What should I do? A copy of your site keeps the original site’s img.pro connection. On the copy, go to **Settings > Bandwidth Saver** and click **Disconnect and keep images**. If you want the copy to use img.pro too, connect it again afterwards (any key works, even one for the same App): it then gets its own label and copies its own images, and never touches the original site’s. While a copy is still connected as the original, deleting media there also deletes the original site’s copies from img.pro. Never click **Delete images from img.pro and disconnect** on a copy that is still connected as the original: it deletes the original site’s images. ### What happens when I delete or edit an image in WordPress? Deleting an image deletes its copies from img.pro. Editing an image (crop, rotate, scale) creates new files, which are copied the first time a page shows them, or right away with **Copy to img.pro**. WordPress keeps the previous files so you can restore them, and posts may still use them, so their copies stay on img.pro until WordPress deletes those files. ### How do I remove my images from img.pro? Go to **Settings > Bandwidth Saver** and click **Delete images from img.pro and disconnect**. This deletes every image this site uploaded and forgets the API key. Uninstalling the plugin does not delete anything on img.pro, so you can reinstall and reconnect to the same App without uploading again. If the site’s address changed since it first connected, a reinstalled plugin cannot find those copies and uploads the files again, leaving the old copies in your App. To avoid that, click **Delete images from img.pro and disconnect** before uninstalling. On a copy of another site, such as a staging copy, use **Disconnect and keep images** instead. ### What happens if img.pro is unavailable? Each image keeps a copy of its original URL, and the browser falls back to your server if img.pro does not answer. Visitors still see every image. Copying waits and tries again later, without marking your images as failed. If it waits for a long time, click **Try again now** on the settings page to try again right away. ### I use a page cache. When do images switch to img.pro? Image URLs are chosen when a page is rendered, and a cached page keeps the URLs it was saved with. The first time a page is rendered after you connect, it asks for copies of its images and still shows them from your server, and your cache stores that version. Once the settings page shows nothing waiting to be copied, clear your page cache to switch those pages to img.pro. ### My posts show images from other websites. Are those copied too? Yes, unless you turn off **Images from other websites** in **Settings > Bandwidth Saver**. WordPress shows any image a post points to, wherever it is: an image inserted from a URL, another website’s image, or your own site’s images at an earlier domain. The first time a page shows one, img.pro copies it from its address, and from then on the page loads the copy. Each copy counts as one image in your App. An image at your site’s earlier domain that WordPress recognizes as one of your media library files (it adds that file’s sizes to the page) uses the copy of your own file instead, and so does an image at your own address with or without www. These keep loading from where they are: * Images img.pro cannot reach, such as ones on a local or private address, and images whose website refuses or fails to send them. * Tracking pixels and images from ad and analytics services, which have to keep reaching their own servers. * Addresses that change from one view to the next, such as signed or expiring links. * Images in a preview or in a post that is not published yet; they are copied once the post is public. Copy only images you have the right to use. A copy is made once: if the image at that address changes later, the copy does not. An animated PNG from another website becomes a still image, like any PNG on img.pro. Copies stay in your App, also after a post stops showing them or you turn the setting off, until you click **Delete images from img.pro and disconnect**. Developers can leave out more images with the `imgpro_cdn_copy_remote_image` filter. ### Can I use my own domain for image URLs? Not at the moment. Images are served from img.pro’s own domain. ### I used version 1.x. What changed? Version 2.0 replaces the old managed CDN and the self-hosted Cloudflare Worker with img.pro. Bandwidth Saver no longer uses the old service, so after updating your images load from your server until you connect an img.pro API key. Old settings, subscriptions and custom domains do not carry over. ## Recensioni ![](https://secure.gravatar.com/avatar/4cf7264e81382090ae5f403198e0bb7f64a4430463a5adf7bcaf8e93b9cac43b? s=60&d=retro&r=g) ### 󠀁[Selfhosting: Works](https://wordpress.org/support/topic/selfhosting-works/)󠁿 [kubo6472](https://profiles.wordpress.org/kubo6472/) 20 Gennaio 2026 14 risposte Been using the selfhosted option in production for months now.
