I have a caption in an image gallery that is not displaying in IE7. Here is the page:

http://www.westhartfordfence.com/products/gates/
In Safari, Firefox and IE8 you should see "Specrail Berkshire Gate" right above the large photo in the gallery. This is not appearing in IE7. I think I've narrowed this down to the negative positioning of this element but I don't know how to fix it.

I am using the Gallerific image gallery within a Concrete5 CMS. The original layout has the caption underneath the photo. I want it up top and that's why I have the negative value.

Here's the CSS and the PHP used for layout:
