Compatibility problems with IE

We are having problems with our family and friends blog suddenly not acting right in Explorer. http://www.whippleworld.com

Loads and looks fine in FireFox but loads slow and some photos don’t come up in IE. First problem we noticed was that our tag cloud started only shows a fraction of the tags. Then no photos would come up in Explorer after the “more” command. In other words, in IE you’d see the first picture but none below “read more” once it was clicked. If you look here, the NGG works fine in FireFox but won’t load the thumbs in IE. http://whippleworld.com/?page_id=6190

And and all help would be greatly appreciated!!
