I'm a web designer & developer that is trying concrete5 out for the first time. (I switched from Wordpress)I love concrete5's dashboard and overall CMS, but one thing Wordpress seems to have on concrete5 is the vast sea of choices for add-ons and plugins.

I'm trying to get my hands on an image gallery script that does a few specific things.
Obviously I want it to integrate with concrete5 more specifically with the files and filesets system. What I need the script/add-on to do is display the first image from each fileset as a thumbnail(automatic resize would be nice) and once the thumbnails are clicked, a viewer pops up in a lightbox/thickbox displaying the image and also thumbnails of the rest of the images in the fileset. (something like this <a href="http://concreteplay.asmiller.com/index.php/galleria_demo/"> in the thickbox)

It would be amazing if I could find one script to do all of this, but that's a long shot, so I was thinking I could mash a few different scripts together to get the desired outcome. What I desperately need is part that selects the first image from the fileset and displays the thumbnails. (my PHP skills are beginner at best,so it would be difficult for me to write my own script.)

Any help at all would be appreciated.
