AGI Picture Editor... APE... ... ... do you have the name of who created it? Credits in a help-file or a .txt-file or so? If it's the one I think it is, none of us really know how to use it. I myself tried to download it, and I think I didn't even manage to find it. If it's the one made by Jocke, we can help.
As for the programming, it's best to check out the tutorials at
Agidev.com (although it seems down at the moment). They explain all the basics. I myself learned it by reading them and fiddling around with the template game, then fixing a bug in another game. All by all, it takes a week at most. If you've got any questions 'bout the tutorials 'bout programming or anything else, feel free to ask and we'll gladly help
