Drag drop target

Hello,

i’m kinda new to flash and i need some help. I’m trying to make a drag drop puzzle like this one. I can do the drag and drop bit, but does anybody know how you make a target in witch the picture can fit exact?

For example, when you drag the picture over the area where you want to put it, but it isnt an exact fit, the puzzle itself makes it an exact fit… If you dont know what i mean you can follow the link and than drag and drop a bit…

Thanks!
