Hello once again,

I'm trying to create some new images for books I need, but whenever I use my image in book, only white square appears in game. I tried it with both tga and dds created in GIMP. The image adress written in CS is definitelly correct, as other book images (those not created by me) work well. Do I need to save it with some special settings?

Is your image 256x256 pixels?
I believe that is the size you need.

I figured it out. The images in dds format need to be compressed DXT3 compression algorithm. Which by the way needs image with dimensions that are powers of 2. I also discovered it works only with width and height differing no more than 1 power. At least during my testing image 128x256 worked, but 128x512 failed to get compressed by DXT3
