Forum:Where Can I Get...

Where can I get the image files of the NCR posters and the logos for all the casinos from the game? I know everyone is gonna shout "GECK" But I don't have Fallout New Vegas on my computer. I don't think the Geck will work for me unless all the files from the game come included in the program. Trust me I've looked on the wiki. I want these images for desktop backgrounds and screensavers.
