This is by design and not by accident. When I was backing up the database last night, I noticed the attachments were taking up MORE THAN HALF of the database's file size. So, I have shut off attachments.
Now, if you want to post an image, you'll need to use photobucket or some other free image host to store the picture and use the forum's vBcode image function (found in the image editor). It's the little "picture of the mountain" button on the editor.
