Okay, sounds good. Would you rather images in TGA, or PSD format? They have built in Alpha channels, and would probably make it easier if you could support them. Other than that i support JGP if the game is getting memory hungry, although i dobt it would cause its 2d. Also i can do all of the formats that photoshop can write to (pretty much everything). If you're not sure what you're using, you probably wanna go with an uncompressed format like BMP.

I can make these have caps (notice you can see through them ) But i think after i model the rest of the logo it might be nice to have them see through.
