Question [Q] Question about DCIM folder on a brand new phone

So I was cleaning up the internal SD card after flashing over to CleanROM and I noticed that the DCIM folder had a couple hundred mb of data in it. Sadly when I tried to stop the delete the folder was already gone. My question is what was in there.. I had not even opened the camera yet since I had owned the phone. I tired to dissect an odin image but coudln't find anything to relieve my curiosity. Does anyone know if there are pre-loaded images or something in there?
Current Device: Samsung Galaxy S III
ROM: CleanROM8
