Basically, the rules are:
- 1280X1024 minimum. Providing other, lower resolutions is fine, so long as there is a copy of that resolution (or higher.)
- No Jpegs. (The compression results in nasty little boogers and static in the image. Remember: you can always ADD the boogers, but you can't take them away. Jpeg compression is irreversible.)
- Naming a specific release of Puppy in your image is allowed, but you probably won't win, because I have 2 installations of Puppy.
- Bonus points for providing it in XCF form as well (just make sure you don't forget the layers.)
