OMG, I feel so goddamn stupid.

My image is now shown correctly, among the mirroring. The header is useless to me, so I want to get that out of the screen.

I looked on the Wikipedia page and i found out that the header is 14 bytes. That means that I don't want to copy these first 14 bytes to the buffer.

But the mirroring I can't 'redo', i don't understand why the image is mirrored and I can't find out how to solve it.

I can't edit the post, i can't find it...

I solved it. The problem was in the fact that I retracted the x-pos and the offset of x in the image, so that is why it was mirrored.
