If your running the classic version of DAoC, they are not a .jpg format. If you are using Shrouded Isles or Trials of Atlantis they are saved in your DAoC directory as .jpg files. Which means you can just double click them and you should be able to view them with media viewer or your default program. They will be in C:\Mythic\Camelot for example, depending on where you installed the game. :)
