They are in a folder together, but they don't seem to work together, every image in the game I'd replaced by that little image of a peice of paper with a hill on it
I just downloaded it and tried it myself, it seems to be working correctly. I'm genuinely not sure why they wouldn't be showing unless you have the folder sitting too deeply in your harddrive (like in Program Files(x86)) and there is some sort of permissions issue. And using the web hosted version shows the images just fine?
