Images loading in Firefox & IE, but not Chrome or Safari

Images loading in Firefox & IE, but not Chrome or Safari

I have a jQuery based gallery ( http://www.brandonboswellphoto.com/richmond_wedding_gallery.php) that will load thumbnails to the bottom of a page, however for some reason these images only load on Firefox and IE (Not Chrome or Safari). I'm not sure this is due to jQuery completely, but does anyone know why this is happening?

Thank you,
Brandon Boswell
