Description
ARWD List Image Size URLs adds a clean, copyable list of every registered image size and its full URL to the attachment detail screen in the WordPress Media Library. When you click on any image, you will instantly see every size WordPress has generated, along with its name, pixel dimensions, and direct URL.
WordPress automatically generates multiple image sizes for every upload, including thumbnail, medium, medium-large, large, and any custom sizes registered by your theme or plugins. By default there is no easy way to see these sizes or copy their URLs without digging through the file system or writing custom code. This plugin solves that problem in a lightweight, no-frills way.
Clicking a URL selects it instantly for copying. No JavaScript is required, no settings page, no configuration. Just activate and go.

FAQ
-
Where do I find the image sizes and URLs?
-
Open the Media Library and click on any image to open the attachment detail screen. The list of sizes and URLs appears in the fields panel below the image details.
-
Why are some of my registered image sizes not showing?
-
Only sizes that have actually been generated for the image are displayed. If an uploaded image is smaller than a registered size, WordPress will not generate that size and it will not appear in the list. You may need to regenerate thumbnails if you have added new image sizes after images were already uploaded.
-
Does this plugin affect the front end of my site?
-
No. The plugin only adds information to the WordPress admin area. There is no impact on front-end performance or appearance.
-
Does it work with custom image sizes added by my theme or plugins?
-
Yes. The plugin retrieves all registered image sizes, including those added by your theme or any installed plugins via
add_image_size(). -
Does this plugin require JavaScript?
-
No. The URL list is plain HTML and URLs can be selected and copied without JavaScript.
-
Is this plugin compatible with the block editor?
-
Yes. The attachment detail screen where the size list appears is the same in both the classic editor and the block editor media modal.
