Gallery page not loading

Can you check this page? <a href=”http://ghajnsielem.com/foogallery/
“>http://ghajnsielem.com/foogallery/

Im migrating from nextgen to foogallery however when i insert a replace a nextgen gallery with a foobox gallery it takes ages to load or it doest load at all. What may te problem be?

Also, is it possible to display just 30 photos per page with pagination / ajax option similar to nextgen? Sometimes i have over 150 photos in a single post.
