I'd use a button with no border as a spacer between the images with a script
like:

on dragEnter
  set the acceptDrop to true
  set the backgroundColor of me to red
end dragEnter

on dragDrop
  -- do whatever
  set the backgroundColor of me to ""
end dragDrop

on dragLeave
  set the acceptDrop to false
  set the backgroundColor of me to ""
end dragLeave
