## Description
Are you concerned about being held liable for violating copyright law, would like
to start crediting owners or [AI-generated images](https://imagesourcecontrol.com/blog/mark-ai-generated-image/)
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**.

**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 or below the image
* Embed a complete image credit list with thumbnails on your website
**Label AI-generated images**
* [Mark AI-generated images](https://imagesourcecontrol.com/blog/mark-ai-generated-image/)
with a label that indicates the image was created by artificial intelligence.
Following the EU AI act
* Available icons: AI, AI-generated, AI-manipulated
* Show only the icon or add a description text to it in the image source field
**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 the caption overlay

or the uploader’s name
* Warn about missing image sources
* Manage, display, and link available licenses
* Enable the features for any files in the media library or for images only
* Filter the media library list by images with or without sources, or only those
using the standard source
**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.

[See Pricing](https://imagesourcecontrol.com/pricing/?utm_source=wporg&utm_medium=link&utm_campaign=pricing).
**Media Trash**
Move images to the trash instead of directly deleting them permanently. This eases
the test if a deleted image was actually unused and allows for easy recovery if
it was not.
* Enabled the module in the settings
* Media Trash has its own menu under _Media > Media Trash_
* Clear the media trash in bulk
* Recover trashed images with one click
[See Pricing](https://imagesourcecontrol.com/pricing/?utm_source=wporg&utm_medium=link&utm_campaign=pricing).
Btw., Image Source Control is a suitable alternative to the discontinued or closed
plugins Image Credits, [Credit Tracker](https://imagesourcecontrol.com/blog/credit-tracker/?utm_source=wporg&utm_medium=link&utm_campaign=credit-tracker),
or FSM Custom Featured Image Caption.
### Instructions
Take a look at the [Image Source Control Documentation](https://imagesourcecontrol.com/documentation/?utm_source=wporg&utm_medium=link&utm_campaign=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 `` 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](https://imagesourcecontrol.com/documentation/#remove-nofollow-from-all-source-links).

### [Excellent plugin with top-notch support](https://wordpress.org/support/topic/excellent-plugin-with-top-notch-support-11/)
[markisu72](https://profiles.wordpress.org/markisu72/) ମଇ 21, 2026 1 reply
There are many excellent plugins out there and this is no exception. 5 out of 5
stars!But what is exceptional is the support… every now and then you stumble upon
questions or challenges everywhere and what for me makes the difference then, is
how responsive and helpful the support is. The real quality of a plugin shows in
the supportiveness and speed of the support if you face issues. And here, this plugin
deserves a 10 out of 5 stars…!

Ich verwende das Plugin mittlerweile auf 4 Websites. Es ist eine
wirklich große Hilfe, besonders bei der Verwaltung größerer Bildmengen. Nicht nur, dass dieses Plugin ein hervorragendes Tool ist. Nein,
der Hersteller bietet auch einen hervorragenden Service mit sehr kurzen Reaktionszeiten
und schnellen Lösungen. Mir wurde bei der Anpassung an
das Avada-Theme sowie bei der Beseitigung eines Bugs hochprofessionell geholfen.
Hinzu kommt auch noch die Erweiterung zur Stapelverarbeitung von Bildern. Ich kann dieses Plugin nur empfehlen.

We’re using Image Source Control to manage image attributions on our website, and
it works flawlessly. The plugin is well thought out, reliable, and does exactly
what it’s supposed to do. What really stands out is the amazing support: We had
a specific issue with the Avada theme, and the developer took the time to investigate
and even provided a solution – truly exceptional. This level of personal and competent
support deserves more than just five stars. Highly recommended!

If you are looking for a plugin to manage your image sources – look no further.
We have this plugin on many sites running for years without issues. The best thing:
The excellent support of Thomas – even for the free version. Thank you! A+++
