[HALP!] How to assemble ripped LegendOfMana backgrounds?

[Ultimecia]

I got this program called Stitch Studio to help me assemble the freaking huge sheets of Indiana Jones and Guybrush Threepwood, among others. The sprites themselves didn't needed assembling, but they were +980 sprites in different files. The program can cut down the images into smaller pieces with a fixed width and height, and then you can re-assemble them making the tiles something like 1 to 5 pixels apart and then re-organizing or assembling them in a proper way in photoshop or whatever program you use.
