Comment 4 for bug 1080090

So this seems to work. I didn't use your image files for the test - I copied and renamed the Lubuntu ones since I knew they already worked and I wanted some that showed the change from standard ubuntu - I had been wasting time looking in the code, trying to figure out why they weren't showing, but it seems that it wasn't the code but rather the images themselves that are invalid. So when you replace them with working copies it should work.

I tested it on 12.10 because I have a 12.10 DVD. I strongly recommend you run your own tests before promoting the code. That way you'll know whether your image files work. If you need help, just ask.
