We just released version 1.1.3 of our Image Source Control Plugin for WordPress. It comes with a shortcode for a paginated list of all images connected to posts and pages.This might help you and your readers to easily find images you had seen before, but don’t remember exactly where.
The feature is still in development and linking to the posts will come soon. We just wanted to release the basic functionality before starting to work on the more advanced version 1.2 of Image Source Control.
You can download the newest version already on WordPress.
