Adds source name and URL fields for media uploads along with a shortcode for displaying image credits for all images within an entry, including its featured image.
WordPress natively doesn’t provide the ability to manage where you’ve pulled different media from, so this can be helpful in making sure you provide links back to the contents’ creators.

Ever wanted to give recognition to the people that helped you produce a given blog post? All Due Credit allows you to include a 
list of names along with any post you write, to serve this very purpose. Each name listed is accompanied by text label that reveals 
what their role was.
You can add the following labels:
<ul>
<li>
Written by
</li>
<li>
Co-written by
</li>
<li>
Edited by
</li>
<li>
Reviewed by
</li>
<li>
Thanks to
</li>
</ul>
Each name can be accompanied by a Gravatar, as well as a homepage link.
All Due Credit currently requires some manual steps to use. For example, whenever you want to add a name to a post, you have to 
add a Custom Field manually, respecting the right spelling of text label. (See the ‘Usage’ tab for more information) While this is completely functional, I will eventually make it friendlier, where you’ll be able to select from a dropdown, or 
something simple like that. Despite this, I’m happy with using All Due Credit on <a href="http://www.mattrefghi.com/wordpress/" rel="nofollow ugc">my own blog</a>, 
and figured some of you may appreciate the same opportunity.
The design of All Due Credit was inspired by <a href="http://www.funnyordie.com/" rel="nofollow ugc">Funnyordie.com</a>.

All Due Credit

Credit those who helped by including a stylish list of names after any post, potentially including a Gravatar and link for each.
