I am having trouble with a slider I've added to my Wordpress-based page. It loads the first image correctly, but then loads the one of the first entry in the blog and shows it for all other entries, with the right image being shown briefly as the slide passes to the next entry. After one cycle, it starts loading correctly. It's driving me crazy!!

This is the page

Any help would be much appreciated
