NextGen Showing Wrong In Internet Explorer

So I have a NextGen widget, that displays random images, in my sidebar. It displays just as I’d hope, in Firefox.

For some reason, it is showing up vertically, in Internet Explorer. Any idea, why this would be happening? And maybe, how to fix it?

Here is the site:

Thank you, I really appreciate your time.
