I have a forum dedicated to nature and wildlife and I have with me 1000's of photos on these subjetcs. Plus I also get every week hundreds of photos of natural sights clicked by my friends all over the world. I would like to post all these to my forum(phpBB) which has sub-forums dedicated to wildlife,mountains,deserts,etc. I want to develop code which will automatically search my hard disk for the photos and upload them to my forum by starting a new thread or post in older threads. I will be the only poster posting as the administrator. Username and password would be hard-coded and it should automatically search my HDD every weekend and post the stuff in my forum.

Has anybody developed a class that does this ? If I need to do it on my own, what built-in classes/resources should I use and what should be my coding steps/strategy ?
