In TFT, What Image Formats do I use?

Im making a campaign, but i need to know what formats my images need to be.

- For the map loading screen, .tga, .bmp, .blp? what do i use?
- For the Cinematic Fade Filter, What do i use?
- and Can you change the campaign screen? or does that require 3dx files and such?

Thanks

I know the custom loading screen is .tga theres guides on it at warcraft3iii.net the others i'm not sure
