jcarousel lite callback?

jcarousel lite callback?

Hi - I am using jcarousel lite on this page:

the photos are being fed from an included php file which is pulling the photos from a picasa web album.  the php page takes a few seconds to run and i would like to have some clean way to indicate that the gallery is loading while this takes place - weather it is with some kind or modal window or better yet buy having the jqcarousel hidden while its loading and display an ajaxloader image.

but i think the key is being able to know when the jcarousel lite is loaded... i don't think jcarousel lite offers a callback function for this, does it?  how could I accomplish this?
