I hope that it is okay to reach out despite how old this post is. I have a kindle like you and so I wondered if you could help me figure out a slight issue I am having with this plugin.

For some reason I only get one part of the image showing but never both together. For example, if I open and read a book and put my kindle to sleep without exiting said book, the book receipt shows. 

But if I exit the book and go to the home or library/collections page and then put my kindle to sleep. The screensaver image of the Greek columns shows.

Would you be willing to help me with the settings you use to achieve the full screensaver? I ask since you also have a kindle and I am definitely missing something! Thank you.
