Skybox with Gimp /solved\

[RawkBandMan]

I will do this fast because I don't have much time. I downloaded a texture from cgtextures:
Medium 4096x683 (0.7MB)

Then I opened it with gimp like this:

Then I pasted each section of the sky into 512x512 picture as layers (sorry about the language in gimp)

Then just change to .dds and it should work. Apparently I noticed a thing about level editors selection thing: you better change the name of the skybox file youre trying to get to show in there, because it doesn't seem to show ones with the same name.

Never Mind, but how did you get them into pictures? They just go as regular layers that the picture goes away if I delete the Background picture.
