Image Source Control Lite – Show Image Credits and Captions


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 illustrations.

Image Credit layouts

Choose between different credit displays:

  • List all image sources below the content of a specific page or place the list manually
  • Show an image caption overlay above the image
  • Embed a complete image credit list with thumbnails on your website

Frontend Features

  • Display image credits in the content, for image galleries, images added by shortcodes, and featured images
  • … see more listed under Premium features below
  • Define the layout and position of those attributions
  • Attach the Per-page list automatically, by using a shortcode, or with a PHP function
  • Display image sources on archive pages
  • Link to the copyright holder and include a link to the image license

Backend Features

  • Add credits for any image file uploaded to the Media library
  • Dedicated image source fields for the following blocks: Image, Cover Image, Featured Image, Media & Text
  • Quickly assign a centrally defined source to any image and choose three options: hide image sources for these images, show a specific source (e.g., your name), or the uploader’s name
  • Warn about missing image sources
  • Manage, display, and link available licenses

Featured Image Caption

ISC Lite works for Featured Images. By default, you will see the image credits options in the media library and the featured image options in the block editor.

The featured image caption shows in the Per-page list with all other image sources on the page.

Check out the premium features to display the image caption overlay for featured images.

Take a look at the Image Source Control Documentation.

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 [isc_list] in your content editor or a text widget.

Use [isc_list id="123] to show the list of any post or page.

Use the PHP code <?php if( function_exists('isc_list') ) { isc_list(); } ?> 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 [isc_list_all].

Use [isc_list_all per_page="25"] to show only a limited number of images per page.

Use [isc_list_all included="all"] 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 instructions in our documentation.

  • display a list with all images of your site and their sources

This plugin helped ease my workload in setting up the website as I use a lot of royalty-free images that needed crediting. The plugin is easy to set up and after adding every image, you can immediately enter the source and url so that it is properly credited. One feature I would like to suggest is to add a setting to turn on or off the border lines, for ease of use without having to enter CSS code. Currently, no border lines are shown and when an image is inserted in multiple pages, it looks very messy on the credits list. The great part about this plugin is the support. I had a problem with the plugin showing up on my translated website and Thomas helped me resolve it quickly. It is fantastic for a free plugin which is better than some paid ones. The exchange I had with Thomas can be found in the support forum under the heading "Credit list not showing on translated page" Overall, very satisfied with this plugin and the support provided. Highly recommended plugin!
