I just asked the same question. Here's the reply I received (it worked):

Stonewalled,

Most forums don't host their own images, so you'll have to upload the image somewhere else. You can either use photobucket.com or imageshack.us. I use imageshack because it does not require registration. Once you upload an image there, you will be given a direct link to it. Click the image hotlink below your post and give it the URL. Problem solved. Also, this question has beeen answered quite a few times before. Try doing searches in the Internet Gambling, Computer Tech, and Other Other Topics forums before asking what appears to be a simple problem.

When using the search feature, put a + in front of all words you want to include, like +search +feature or something liek that.
