This plugin adds credits, link and license fields to media uploads and offer several options to display image credits on your posts and pages. You can either:
<ul>
<li>Use the [image-credits] shortcode. Optional attributes are <code>sep</code>, <code>before</code>, <code>after</code> and <code>template</code> (use curly brackets instead of square brackets for placeholders).</li>
<li>Use the <code>the_image_credits()</code> template tag. Optional parameters are <code>sep</code>, <code>before</code>, <code>after</code> and <code>template</code>.</li>
<li>Let the plugin automatically display the credits for you, before or after the content or overlaid above each image.</li>
<li>Use the widget to display the credits in the footer or the sidebars.</li>
</ul>
See the settings page to choose how you display the credits, including the HTML used to build them.
This plugin is a fork of the <a href="https://wordpress.org/plugins/image-credits/" rel="ugc">Image Credits plugin</a> by <a href="https://profiles.wordpress.org/adamcapriola/" rel="nofollow ugc">Adam Capriola</a>. It is 100% compatible, if you are already using the Image Credit plugin just replace it with this one and it will work about the same way, except you will have more control.

This plugin adds credits, link and license fields to media uploads and offer several options to display image credits on your posts and pages.

Do you use stock photos from big stock photo sites such as Fotolia, istockphoto or 123rf on your site? Then you probably need to include the image credits / author credits with each photo to avoid legal issues.
When searching a lightweight solution for this, you might have stumbled upon complex plugins.
Our approach was to keep this plugin as lightweight and simple as possible – to make sure every one of your wordpress contributors will understand how to use the plugin.
<ul>
<li>Our plugin simply adds a textbox below the text editor.</li>
<li>You can then use the shortcode [image_credits] to let WordPress show the full list of image credits, separated by the URL where the images are being used. Many webmasters choose to show the image credits on their imprint site, others create separate pages for it.</li>
</ul>
If you have any suggestions or questions, just ask. We will continue to update this plugin, while keeping it simple and as easy to use as possible.
