Duplicate a mc with an external JPG in it

Hi!
I load an external JPG in a mc, then I mask it using ‘setMask()’ method.
The problem is:
I need to duplicate this clip but I don’t want to load again the same image (I should load it like 30 times). Someone knows if it’s possible to duplicate a mc with an external loaded jpg in it mantaining the loaded image?

Thanks!!! C:-)
