Linked Images do not open up linked address

[suziclue]

This may sound confusing but, I'll try my best. I have users who post an image and include a link to the image to a larger image. When viewing the post, you can see the image but when you click on it..it doesn't follow the link to the larger image. When you hover over the image, it displays a magnifying glass (with plus). Clicking it only shows the same image at the same size. It seems to work fine on this board as you can see with the attachment.

Thanks ahead for any help! Oh I have the Modded Portal version installed.

Sorry had to remove the picture in post for the sake of male members (or even female) getting too carried away.

I know you are sorted with it now, but for anyone reading and has the same issue, it is to do with the highslide mod. All you have to do is upload bbcode.php from a fresh phpBB install to /includes folder.
