Help!! (Need help with a program)

[CutMeMick]

OK, so heres what I wanna do.

A while back I can't remember where I saw this I think it was in a blogspot or chat room. Someones profile as their signtature it had about 20 pictures.

Where it was something like a rectangle but it had all the images in there in sections but the person viewing it could click on the image to view it as a larger image.

I have about 27 very small pictures (4kb to 7 kb) (100x75) that I'd like to fit into one of those things that I described. Since our signature settings only allows for 2 images of [IMG]
Was wondering if anyone here knows of any program that could either do that (what I described) or something very similar. I don't wan't a slideshow/video I just want the images.
I'm sure theres a program out there that can do that.

Thanks for the help.
