I know. I left that on there in the mean time while I figured out the translations. It wasn't even bending the map at all before. The software just sees the image as a blob of data, that you have to tell it how to transform, so it really didn't care that the map had a legend left on it. In my last post, I describe how I finally got it to work. :)
