RE: [PHP-DEV] Image Alpha Channels

Thanks so much for your time sir! I wasn't expecting an answer from such a prestigious source :) I spent almost 3 hours searching for this answer, and (being a fair programmer) I was fairly frustrated that I couldn't find an article on it by searching google or the common php websites FAQ/Forums. Where is a good place to conduct my searches for these sort of advanced concepts, so that I don't have to waste anyone's time asking amatuer questions? Again, thanks for the response... It was most helpful.
