Well, sort of...

Apparently the problem lies in the theme I'm using for the website. This website runs on a Content Management System (CMS) called Drupal. There are, literally, hundreds of themes available for the system. The current theme doesn't allow any content to span across more than a certain number of pixels and will just "clip" the content at that point. Unfortunately, I really, really like this theme.

The solution is to use a different theme, but only when you're in the forum. Drupal can do this, so I have configured it that way. When you go into the forum, the header will look quite different. When you go to the main part of the site, you'll see my preferred theme again. This will do until I can find the right line of code to correct the current theme issue.

Note that this also happens in the gallery of magazines when you try to see the page in its full size. However, since the only reason I can see to view a magazine page there in all its glory is to download it, I don't see this as a problem. What you download would not be cut off as the image appears to be.
