I found an image I want to use as my signature, but I have checked everything and it doesn't seem to work. I put the proper tags in, with [ img ] and [ /img ] on either side of the URL (I added the spaces here because otherwise it shows the little "file not found" blue question mark). I double checked the URL to make sure it works, and it does. It's smaller than the maximum size, and only takes up 4 kb. Any idea why it isn't working? Do I have to have a certain number of posts?
