I understand that you need to protect against spam. I'm a moderator on a writing forum where we have big problems with Spam. But could you have another way of posting pictures that doesn't need a link, or else introduce posting links after 5 posts. I've found myself posting pointless posts just so I can show a picture to get some help.
