Need xml gallery tut like this site

hi, i built this site for a friend
now we are planning on an site make-over to the gallery.
the problem is the gallery loads up each gallery in one go. we are trying to to make it load up per image with preloaders.

here is the gallery site: **
i need a tutorial that is similar to the gallery but has preloaders per image. saves the user from downloading the whole gallery in one go. Also i prefer it to be XML and AS3.

could anyone help? ive tried alot of tuts but they werent what i was looking for.

p.s i had to use tinyurl because i didnt want this thread to be up on google.
