Issue with Lightbox and IE 7,8
 

My lightbox doesn't seem to be working in IE 7 and 8. Image doesn't pop up screen just goes blank. Is there an issue with the lightbox script possibly conflicting with the HTML5shiv, css transitions, or the images being in a table? Site is here www.picturesquestudios.com/html/portfolio.html.

Any help is appreciated

Used IE8, things worked for me.
