is it possible ? (displaying picture after booting linked to system time /date)

[duncid]

Hi everyone,

I'm a product designer and for prototyping issues, I was wondering if it was possible, starting from a Kindle (1, 2 or DX) to reprogram the device to execute right after booting a simple slideshow of images and eventually to link the images to the system clock (dispalying a picture a precise time /date), and how you would evaluate the difficulty of the exercise.

thanks for your time and help !
