Never imagined this to be skull-worthy, so I guess I'd better explain:
I can't take credit for this idea...
@Hacker404's #Full Size Image Gallery and corresponding Thumbnails Gallery stumped me for quite some time, but I think @Hacker404's idea (if I understand it correctly) has basically been reimplemented here for my own purposes.
But, I won't explain what this idea is, here... it's a (really simple) riddle, or something, that you too could find useful.
It's all about the pictures!
(Looking back, this coulda easily been implemented in a "Page" just as easily, and wouldn't hog-up my project-space... but there's some good comments here, so I'm not gonna change it any time soon)
