I'm wanting to give certain members the ability to upload images as attachments. So far all I have allowed is embedding code from free image hosting sites like Photobucket. My question is, has anyone done this with a large forum before and how much storage have you needed? My forum has over 16,000 members and it's a very photo heavy site. I'm going to charge people an annual fee to be able to have this feature to cover the extra storage costs, but I wanted some suggestions on what I should set the limits to so that I don't get myself in trouble.
