If you use Rev 2.9 or later, probably you could use drag and drop 2.9  
implementation.
Or if you don't want to 'move' a 'blendleveled' image, you should  
have a look at two things:

1. The 'grab' command.
2. A code snippet that has been posted many times in this list and  
you can call from every piece of your jigsaw puzzle:

local sAllowDrag
---------------------------------
on mouseDown
   put the mouseH & comma & the mouseV into sAllowDrag
end mouseDown
---------------------------------
on mouseMove pX,pY
   if sAllowDrag is empty then exit mouseMove
   set topLeft of this stack to globalLoc(pX - item 1 of sAllowDrag &  
comma & pY - item 2 of sAllowDrag)
end mouseMove
---------------------------------
on mouseUp
   put empty into sAllowDrag
end mouseUp
---------------------------------
on mouseRelease
   mouseUp
end mouseRelease
