If you look at my gallery page http://bigbananacar.com/pics.php
in the browser Chrome, you'll notice that when you mouse over the four images in the top right corner ( and part of the images to their left) they are not clickable.
All the other images on the page work fine.
However, in IE9 everything seems to work just fine.
When (in Chrome) if you enlarge one of the other images, the area of that image to the right (over the top four thumbnails below) is a dead zone and not clickable.
And the transformation from one image to the next is very harsh in IE but not Chrome.
