One way is buttons.  You won't need 50 image objects, but you will need 
50 button objects, of which you set the icon to the ID of whatever 
source image you have.

set the icon of btn movingBtn1 to the id of img sourceImg
repeat with x = 2 to 50
   clone btn movingBtn1
   set the name of last btn to ("movingBtn" & x)
end repeat

You should wind up with 50 buttons all referencing the same source image 
(make sure you disable all the properties of the original button so it 
doesn't look or respond like a button object).
