title: Eclipse gives "invalid resource directory name" when I add a non-resource PNG file to my Android project
body: <p>I want to associate a PNG file with my Android project in Eclipse, but I don't want to actually publish it - it's just a higher-resolution version of the various icon.png files that I used to generate the icon.png files. But wherever I put this PNG file, I get the error "invalid resource directory name". Where am I supposed to put it? I really don't want to put it outside of the project folder, because that would disassociate it from the project!</p>
