Decided to make some changes to the restrictions on who can upload images directly to the forum. Note that this is a trial-run and it's duration may be dependent on how quickly you guys start gobbling up our allotted storage space on the server.

So at the moment, here are the limits:

Post Attachments:
New Users (under 15 posts) - N/A
Basic Users (15+ posts) - 10Mb
Paid Members - 100Mb
Moderators - 100Mb

User Albums (in your profiles)
New Users - N/A
Basic Users - 10Mb
Bronze Members - 25Mb
Silver Members - 50Mb
Gold Members - 100Mb
Moderators - 100Mb

We'll see how this goes. Don't know what the cost is to increase storage space off the top of my head, but that's usually one of the things the hosting companies like to rake you over the coals on - especially when your hosting plan includes unlimited bandwidth.
