Thank you for the reply Thomas and the welcome Bruce. I thought that is what would be needed and have told the users of the forums to do that. Imageshack just happens to be the most popular one so I was wanting to let them continue using it. We will work around it though by using another site. Thanks again for the prompt reply.
I am posting this in the security forums as I beleive this is security related. When trying to post a link to an image on our forums (phpBB) I get the following error: Not Acceptable An appropriate representation of the requested resource /forums/posting.php could not be found on this server. In doing some research on the net it looks like it is a security setting on the server and it only seems to give this error when posting an image from like Image Shack or one of the other free image hosting sites. I am guessing this is related to some of the vuleralbilities with images and phpB
