Sweet! It's about time Thailand had something nice on one of these websites! lol.
Well the issues come with storage of pictures and the retrevial. It'd probably slow down the system, but I think if you make the picture small enough (maybe a thumbnail on the side of the airport map page after you buy a gate), it'd work out. Plus don't we all collectively have enough pics of airports to send to stephen and the gang? I know I have plenty of BKK (Old and New), NRT, HND, and MCO pics to spare. That or find a site like airliners.net that's dedicated to only airport pics and get em off of there.
