I mostly used Gimp to make maps. For sprites I use Spooky Sprites, but occasionally use gimps a bit at first and import the picture into spooky.

Spooky works under linux nowdays (and possibly under windows, although I haven't tried for a long time), but when we started with dom-ppp I used corel draw or something in windows and exported it to the atari version of spooky. At that time dom was an atari game. We switched to linux after a few months, but the atari conversion of sprites took quite a while to disappear.
