Gus, Just a note to clarify the discussion about compressed Targa files (I'm sure you know this, but for the eavesdroppers). In the .TGA format, a compressed file will always be smaller than the uncompressed file, because repeated runs of pixels will be compressed (run-length-encoded with a count + color), and individual occurences are flagged as "raw" pixels. Admittedly, a programmer could ignore the "raw" concept and load up the file with an extra byte for the count at every occurrence. I don't recommend it <g>. Kevin Krell – Computer Support Associates
