What about this?

You could group the image, so the image will always stay (and be  
visible only!)
within the rect of the group (lockloc!)

And you might use a setprop-handler to "trigger" the zoom-in/-out of  
the image.

Like this in the image script:

on mouseenter
   set the must_zoom of me to "in"
end mouseenter

on mouseleave
   set the must_zoom of me to "out"
end mouseleave

setprop must_zoom what
   if what = "in" then
      ## do your zoom-in routine here...
    else
      ### do your zoom-out routine here
    end if
end setprop

Simple, clean and elegant :-)
