Hmm you might what to post this in the Computer Tips sections but let me see if I can work out what the problem is. Ok: you went to manage attachments, chose a file, chose upload, which is what I've just done. Lets see what happens
Right that worked. Did you by any chance paste the link into the body of your post? Because if you do that I know you get the same effect as you're seeing. You don't need to actually put the link in: if you've attached it as a file it will come up automatically. However, I'm not sure how you get the image into the body of the text. It must be one of those buttons at the top when you post.
Right I just checked in the computer tips sections and swa something that says that if you try to insert more than mone picture, you'll get links like you have Maggie. So that must be it: 1 link gives a picture, more than 1 link and you get clickable links.
