How do you make cloud and aurora textures for EVE packs?

Title says it all...

Textures are, essentially, pictures. So you take a graphics program (GIMP is a free one), and paint them/cobble them together from photos/sacrifice a virgin to summon them. Finally, you export them in the file format that the program using the texture expects to receive.

In order to find out what that format is, download EVE, and examine its default textures. Load them into the graphics editor to find out how they look. Perhaps you can even use them as a start and apply your changes to them, for practice. (Remember not to release anything derived from someone else's work that comes with a license which forbids changing and/or redistribution.)
