For image format, why not using RAR compression on a BMP ? With multimedia compression of the RAR compression we got a ratio of 4 > 1. without quality lost. There is also an another way to have very small files : use 256 colors per bitmap which decrease a lot the file size. Finaly there is the PNG format that also use a compression without quality lost. Anyway for the Jpg format, we can use a compression of 90 % with YUV122 sampling and the Huffman optimizations, like this we got an image that look like a lot to the original. Only a few details will disapear. I saw that in Return to Castle Wolfeinstein, they were using Jpg compression for all textures.
