Imageshack takes the filename of the image I uploaded, removes spaces, converts to lowercase, cuts it down to 22 characters, and then adds those random letters and numbers on the end, to avoid filename collisions. It also assigns it to a directory/virtual server for load-balancing. In short: they're random and added by Imageshack.
I may or may not finish this, as I explained before. If I did, I'd finish one game and then move on to the other, how they'd be arranged on the site is another matter.
For the wrapping courses, I'd choose an appropriate cut-off point and go from there. I did try mapping the one you mention, but the water animation made it hard to automate. An Action replay code to disable animation might help there. SMS Cool Spot is my mapping priority now, anyway.
