in reference to webmaster at webnetwizard dotco dotuk who had a rather complicated method of
determining if a GIF had any transparency set ...
imagecolortransparent will return -1 if no transparency is found.
eg:
$transColorIndexMain = imageColorTransparent($mainImgObj);
if ($transColorIndexMain >= 0 ) {
# GIF has transparency ... ;
}
