I agree with sumpin that if it's considered "impossible," then that's just a challenge.
The image replacement suggested could be helpful to me, and although I know what a PNG image is, and how to size one, and even how to create one, I am lost about where to find the default image. I can't find anything like that on my Kindle, and I am looking at all the files and all the "hidden" folders (I think).
Could you give me another nudge in the right direction?
You may assume I have a PNG image of the correct size, and that I can give it any filename as needed - what do I do next?
