Olaf: you said it was raw rgb image data (24bit) what did you mean, btye 1 of the file is how much red first pixel is, second byte is how much green first pixel is, third is how much blue, girth is the read of second pixel etc? How do you calculate the images X and Y? I have also been reading your code in the trunk and can't seem to find what I need to do this, your XCC Mixter shows a preivew of the map I belive, as PNG to! Please advise.

Hey, I've been doing almost exactly the same the last few days.
I've noticed that when you have decoded the concatenated string of all the values in the PreviewPack section, and then use decode5() on it (see xcc mixer) to decompress the LZO compressed data, you'll get a array with all the bytes you need. I believe the G and B values of the RGB array are swapped.
