No.Is the code you wrote available in internet?
No.Did you write the nehe tutorial to load TGA/BMP?
Nothing. But they are easy to load! TGA supports alpha channel (32-bit).What's special about TGA or BMP?
JPG is a lossy format (meaning when it's compressed data is lost. It is not 100% identical to the original image. For computer graphics that's bad!What's wrong with png,jpg?
PNG is better than JPG, but very difficult to load (as in write your own loader class). As I said before, just re save the assets into TGA. Job done.
