The script below works for me here sufficiently elegant:
put (the mouseH - item 1 of the loc of me) into cX
put (the mouseV - item 2 of the loc of me) into cY
put true into movedobject
on mouseMove x,y
if the mouseloc is within the rect of image "big" then
# assuming the "dragged" image is moved within a larger image,
# but - if not - you may remove the line above and the
# "end if" in this mousemove handler
if not movedobject then exit mouseMove
set loc of me to x-cx,y-cY
set the loc of img "hiliteframe" to the loc of me
# "hiliteframe" is a transparent image where only the borders are
put false into movedobject
