Help with Photogallery please, rather urgent

Hi all, have looked at the tutorial at http://www.kirupa.com/developer/mx2004/xml_flash_photogallery.htm and http://www.kirupa.com/developer/mx2004/thumbnails5.htm
and found it most useful. Thank you for that.

However, I need to create a photogallery where I can click thumbnails that do not scroll, preferably predesigned and already placed on my stage, and have the pictures fade in, perhaps calling them from a fscommand folder? Bsically I was wondering what script would be on the buttons I’ve created, to call the pictures from my folder (in the same destination as myflash file) to fade in. I would like to use the Xml file as it seems to minimise loading time, but have no idea how to go about editing the script in flash itself. I do not need captions, just the images. And the thumbnails as I’ve said are to be predesigned, and not just smaller versions of themselves.

Can anyone help me here? I’m not very actionscript savvy and thus need some guidence. Much appreciated…
