Not really software but I cant think of where else to post this.

Im having trouble finding places to host the large files for my maps.
The sites Im referring to are ones like photobucket, where you can upload an image and then share it very easily.
I help run a roleplay on a forum website that doesnt include its own image hosting, so I need one that can host 2k x 2k files that are over 5mb in size.

Any suggestions?
