While it's a very nice graphic, I have to reject it due to it lacking a proper bps file to setup stuff.
For graphics like this, you could put them in FG5 or FG6, instead of FG4. And then, mount them. After that, make a bps patch and include it. Currently as it is, just inserting these graphics will not work from the get go. Once you make these changes, I can gladly accept this graphic.
