Having modified a template I bought off the web I have an issue I can't get my head around.

The site is http://www.carlglanceyphotography.com

When you click on the portfolio tab the images jump to the right of the screen before loading and do that everytime you select a new category.

This doesn't happen when you view the SWF file.

Am wondering if the problem is with the index html doc. The code for this is underneath. Any help/tips would be greatly appreciated.
