1) Naver Kitchen has a great gallery of Korean food as made generally by Koreans living in South Korea. It is a Korean language site, but browsing dishes is not difficult with an online dictionary and a few clicks.
2) You can search Trifood, Tastespotting or Koreanfoodgallery for pictures of Korean cuisine. However, keep in mind that not all of the dishes presented are authentic for Tastespotting and Koreanfoodgallery. If you are new to Korean cuisine, a good guideline to follow is to search for blogs that are written by Koreans or those raised in a Korean household. I will only introduce you to blogs/resources that have been verified for authenticity unless otherwise noted.
