Killing image compression in PBB Gallery

Already posted this over to Pun Res, but I figured I put it up over here too. This issue is really bothering me.

I want the image uploaded without being resampled, except for the thumbnail. It really destroys the image quality, imo.

Looks like maybe http://us3.php.net/imagecreatetruecolor is the culprit? Anyway to either get it to not create the new image and just use the original image OR let it create the image but make it it a lossless copy?

I can't see what's doing it in gallery.php or related files, besides the fact that it's inthere. i.e. I don't see anything that seems easily editable, like "if size then compress by this %" sort of talk.

Anyone know the answer?

Thanks.
