Using flyout example file how to switch the "out" image

New and need help.

I'm using the flyout-more-hotspots example and would like to switch the image when it has flown out.

So for example hotspot name="image1" has url="images/image1.jpg" in its normal (fly state 0), but when in out state (fly state 2) it should use a different image url i.e. url="images/image1_out.jpg".

Many thanks

OK, found out how to do this using:

set(hotspot[%1].url,'images/image1_out.jpg');
