Rails - Jul 2006 - Ajax "Waiting..." flash while round-tripping

I''m trying to figure out how to best allow a user to click a 
link_to_remote (or something like it) that will make the clicked thing 
disappear and replace it with a "Saving..." or "Please
wait..." image
until the server round-trip is complete. Once complete, it needs to 
replace the HTML in that span or div with text from the server.

I imagine it will involve linking to a javascript function that can set 
it to not display the current image and show the "Please wait..." 
graphic. But then getting the AJAX call made from there has me stumped.

Anyone able to enlighten me on this?

What about the :loading option?
