I'm in the process of making an interface texture mod, and thought I'd have different loading screens to go with it.
So what I did was, got the picture I wanted to use, editted a bit so it was to my liking, made it the same size as the others and in .JPEG format. Also I made two images, both different sizes, (I noticed there was two of each picture in the textures folder), one 1280 x 960 and one 512 x 512. I saved them with the same name as one of the original pictures 'loading0' and 'loading0_f'.
But, when this particular loading screen comes up it's just the ominous yellow and black stripes. I'm guessing I've don't something wrong but I'm not sure what.
