Alphabetical Listing??

[XBleed]

I was wondering if there was a mod for this..  I searched but had no luck.

I want the categories to have an alphabetical listing on the top, so users can click "A, B, C, .." and the images that start with only that letter will show up.

I'm told this is pretty easy to do, but I'm no good with php

Sorry if this was already posted, but like I said.. I had no luck finding the topic.

Anyone??
This would be a great mod if it's not created yet.
