Short question: How to copy-paste a pile of images into another pile of images automatically? Elaborated question: Let's say I have two folders containing image files (in PNG format). The first folder is called "backgrounds" and contains a few hundred images named in numbers: 0.png, 1.png, 2.png... The second folder is called "front layers" and contains a few hundred (transparent) images named in numbers: 0.png, 1.png, 2.png... I would like to combine the images from these two folders together, so that all the "front layer" images are pasted as front layers onto the corresponding "background" images. These combined images would then be either saved in a third folder called "finished images" or just overwrite-saved to the existing "backgrounds" folder. It could be done manually, but I would like to know if there is a way to automatize the process. I can make some simple scripts for GIMP, but I can't quite handle multiple files at once and save them accordingly. Any scripting help would be appreciated and any kind of solution to the problem will suffice. Are there other programs than GIMP that might provide this kind of functionality? It's a simple task, but laborious to do by hand. As always, helpful posts might be rewarded with a few thousand rerecords.

needs bash and imagemagick, replace 123 with the number of images you have. 
for i in $(seq 0 123) ; do
  composite "front layers/$i.png" "backgrounds/$i.png" "finished images/$i.png"
done

Thanks a lot, Tub! I'll test it sometime soon.

Works in zsh as well. Moreover, in zsh you can do it like: 
for ((i=0; i<124; ++i)) composite "front layers/$i.png" "backgrounds/$i.png" "finished images/$i.png"

Thanks guys. I'm a lousy Windows user, so I had to install some exotic ports to try those things and it turned out to be a bit cumbersome process. In other words: 
seq: command not found
Oh, by the way, I happen to have PHP installed. So, what might a corresponding PHP script look like?

Oh dear, I'm sorry, but now there's some problem when I try to run the PHP script: 
parse error, unexpected T_STRING in script.php on line 3
I have tried modifying the script in many ways without success. Imagemagick itself is working wonderfully, by the way. Thanks for showing it to me.

Ok, I got what I wanted. Everything is working perfectly now and this saves many hours of my time. Thank you. I'm going to spend those saved hours in experimental Gens TASing, so as a reward for helpful posts, Tub, Warp and LagDotCom, each of you can now choose one game from this page: http://tasvideos.org/ListofIdeas/Genesis.html I'll play all three games through normally and then I pick one of them and start TASing it for a few thousand rerecords. P.S. LagDotCom, don't ask me to improve King's Bounty this time!

oops, sorry about that. I obviously didn't test the script :) I've played Cannon Fodder on the Amiga a lot, but I don't know if the Genesis version is any good. Lacking a mouse it probably isn't. Not sure if it'd be interesting to watch either. So you might as well use adelikat's suggestion ;)

That list is slightly out of date (there is an ECCO movie, etc.) I wanted to say Chaos Engine, but it's not... wait, *looks for Soldiers of Fortune* no that isn't there either. Bah. From that list I'd most like to see Rings of Power, because I have no idea how to play that game.

There is a movie for Ecco the Dolphin, but "Ecco: The Tides of Time" is a different game. There is no published movie for the latter. Anyway, the list may contain some mistakes, so please continue notifying any suspicious seeming thing there, thanks.

It is there, on the "not working" tab. The graphics are not emulated correctly in that game. Ok, LagDotCom's choice is Rings of Power and Tub got Golden Axe 2 & 3. Warp can still choose the fourth one.

Then you should have used the 'for ((i=0; i<=123; ++i)); do <the command>; done' form (with bash). (Btw, I still can't understand why it seems that 99.9% of linux users prefer bash over zsh. What is it in bash that makes it so good? What is it in bash that zsh doesn't have? I could list a ton of things zsh does have which bash doesn't. Whenever you ask some linux user something about the shell, it's *always* bash, only bash and nothing but bash. I don't remember *ever* seeing anyone (besides myself) even mentioning zsh as an alternative. Yet in my experience zsh is so much more advanced than bash.)

I don't *prefer* bash, I just deem bash good enough for my needs, and everywhere I log in (home, university, root server, ..) there's a shell that's either bash or bash compatible. Getting used to zsh-specific functions wouldn't do me much good.

Hey, maTO has made a nice TAS through that game in slightly over 2 hours. You can find his run here: http://www.freewebs.com/suklaalevy/files/megadrive/
