Yes the GS3 has a built-in function to do this. First, open your Gallery then tap menu, settings, turn on "Tag Buddy", and place a check-mark in the box next to "Date".
Then go back to your gallery, select any pic, then start scrolling through your pics. As you scroll from one pic to the next, you will see the date the pic was taken displayed at the bottom. It will disappear after about 3 seconds
