what I need to do is add
<a href="javascript:pixlr.overlay.show({image:'path/to/image.jpg', title:'image name'});"><img src="path/to/image.jpg" width="250" height="150" title="Edit in pixlr" /></a>
around any images that are uploaded. So when you have an image in the admin side it can be edited via pixlr.
I have successfully loaded the required scripts that this requires but need to know where to add the href wrapper (see above) if I can call it that.
