[jQuery] JQzoom help!

hello,
I'm new to JQzoom ( http://www.mind-projects.it/projects/jqzoom/index.php#examples
) and I have two questions;
1) how can I display the zoomed area on load without mousing over the
main image?
2) is there anyway to control the zoom in/out, or does it have to stay
at the current level?
any help would be really great!
thanks for your time,
-Ken
