Are you concerned about being held liable for violating copyright law and would like to start crediting owners properly?
Do you want to give back to photographers and illustrators by adding image credits, so they are rightfully attributed?
Or are you a creator yourself and want to show information on the picture licenses for your image gallery under which publishers can use or purchase your work?
Image Source Control is your go-to solution when it comes to handling copyright-protected photos and delete unused images.

<h3>Instructions</h3>
Take a look at the <a href="https://imagesourcecontrol.com/documentation/?utm_source=wporg&utm_medium=link&utm_campaign=documentation" rel="nofollow ugc">Image Source Control Documentation</a>.
Find a list of missing images sources and other debug tools under Media > Image sources
You can choose to display image sources below the post content or as a small caption overlay above your images. Just visit the settings page of the plugin to enable those options.
Manually included image sources on pages/posts
You can add the Per-page list manually to pages or posts via the shortcode <code>[isc_list]</code> in your content editor or a text widget.
Use <code>[isc_list id="123"]</code> to show the list of any post or page.
Use the PHP code <code><?php if( function_exists('isc_list') ) { isc_list(); } ?></code> within your template files.
List all image sources
You can add a paginated list with ALL attachments and sources attached to posts and pages—the Global list—using the shortcode <code>[isc_list_all]</code>.
Use <code>[isc_list_all per_page="25"]</code> to show only a limited number of images per page.
Use <code>[isc_list_all included="all"]</code> to show all attachments in the list, including those not explicitly attached to a post.
The plugin searches your post content and thumbnail for images (attachments) and lists them if you included at least the image source or marked it to use the default image source.
Remove “nofollow” from all source links
In order to remove “nofollow” from source links, follow the <a href="https://imagesourcecontrol.com/documentation/#remove-nofollow-from-all-source-links" rel="nofollow ugc">instructions in our documentation</a>.
