Loading images via XML

Hi, I’ve created a photo-gallery based on tutorial http://www.kirupa.com/developer/mx2004/xml_flash_photogallery.htm

Each image in this gallery is loaded only after the next button ( or thrumbnail) is clicked… exept first one.
Can anybody help me about what to do if I wish that all images are loaded automaticaly… I mean when first image is loaded and displayd the second image starts loading (in cache or somthing like that) etc.
