Is it possible to replace (not add to) the original behavior?  I'd like to make a very small script that does not allow an image to move once it has been "locked" but it appears while I can add an event handler that will fire AFTER the original fires, I cannot keep the default handler from firing.  Any ideas?

You can't prevent the movement, that has already happened and triggered the change event.  The best you can hope for is moving it back.. see:  MapLock which does just that.

I've used the script and wanted to figure out how to modify.  Any idea why they don't allow it? EDIT:  As it really only affects the GM/DM experience, reduces set up time, and is on the script runner to debug, I hope something could be worked out (on the Roll20 side).
