Themes publishing guidelines
 

I'm doing some themes and i wanted to share them, but i was wondering wether there is any publishing rule, or file naming policy or anything for themes so that it's easier for everybody else to use them.
For example: my player uses several bitmaps for each menu screen, but the divisions on another player with the same screen width may be completely different, should i publish the theme with the images as a whole or pre-cut?
Any ideas?
