Easy way to set date taken as created time(photos)

Is there any easy around way that let me set the created date of my photos from the date it was taken?
I try with a rename script trick but I have to call dopusrt for every file, so it can be a pain in the ass. A way to do this with some kind of command will be great. Any idea?
Thanks.
