I've been puttering around with the Gallery feature here (look at the blue menu bar at the top and click on 'Gallery', which is between 'People' and 'Links'). Not only can you upload images, but you can organize them by categories, sub-categories, asssign keywords, etc. You can also upload thumbnail images for each category.
Here's a little prototype I whipped up: my
TCS Gallery.
I'm amazed that this site hosts images, given that it's free.
You should start a thread for new folks just pointing out things like this. You seem to enjoy messing around with the place and finding things. Maybe it would entice more to stay and use those features if they are not big on just posting all the time.
