title_body: Personal screensaver random from a set on Bookeen Cybook Odyssey In this answer it describes how to set a screensaver image (that shows when the book-reader is switched off/standby).
  
  If you deselect the screensaver the Odyssey shows one of series of (5 or so) images at random. I have not found these pictures as files on the book reader internal memory.
  
  I would like to have my own set of images from which my bookreader would choose, not just the one I can select as with the aforementioned answer.
  
  How can I achieve this? Or alternatively, where do the 'default' images come from (as I think I can figure out how to replace them once I know where they come from)?
upvoted_answer: It is not possible. Right now, you can either select only one image from your own documents, or the random set of Bookeen images, which reside on the partition not accessible by the user.
