Another Forum I am a member of uses the same program as this forum. They have members galleries and also other galleries for pics. You can do separate folders under either gallery. I am not sure what the bandwidth is for that, but they are a very active group with paying members, fund raisers and get togethers.
Here is a link to their gallery section just to take a look:

Hope this helps.
