Forge card pictures; especially Return to Ravnica.

I have download parts 1-4 of the Hi res card images and put them into the res/pics folder that I created. I started up the app and it stated it needed to update by importing all of the decks, card, etc to the applications folder. I did so and it told me delete the pictures in the pics folder and I did that as well. When I started up Forge, I checked the cards and only some Plains and Swamp have pictures. The rest of the cards are still blank.
What am I doing wrong? I downloaded version 1.5.19-SNAPSHOT.rar since the other one just hanged at the loading forge bar.
