Note Submitter: grosbedo at gmail dot com ---- Thank's to the previous commenters for their implementation of a tga reading library in pure php. I tested them, and they work, but not everytime. So I looked on the net for another implementation, and found the de77's implementation working for any tga I could put through the algorithm. The tga.php library can be found here: http://de77.com/php/open-tga-with-php-imagecreatefromtga
