Somehow I can't get to the actual image layer. Whenever I try to select a map, I just get the background. I'm using Acrobat Pro 9 on a Mac, but I don't think that should have anything to do with it.
I believe this only works on versions prior to Adobe Reader 8.1. See the replies above.
Even with a full version of Acrobat? I'm not using Reader for this.
