When you click on one of the larger images in the main content area the PrettyPhoto gallery appears. If you roll your mouse over the main image, a smaller thumbnail gallery appears underneath (the thumbnail images are broken which is another problem I will have to fix later). But when you move your mouse OFF of the main image, the thumbnail gallery disappears. Can someone help me decipher how I would disable the "pp_gallery" from disappearing?

Thanks in advance!
