I was looking for a quick way to post pictures on my Website. I tried using WSS but it's too much work when you have hundred of pictures. Scott Guthrie posted this last week:

ASP.NET Photo Handler: Bertrand has posted a cool photo album HttpHandler for ASP.NET that allows you to easily drop images into a web directory and automatically generate a nice photo album of them (complete with EXIF information, stack sorting icons, etc). Might be very useful for people enjoying holidays this summer. Download the code here.

All I can say is Wow! Just drop a few pages into a website then just copy your pictures into sub directories. Voilà! I can't be easier then that. Thanks for Bertrand LeRoy for this fantastic app.
