Album rotation - multiple images

[NullVsNone]

Could this be enhanced to support uploading multiple images, with a set timer to rotate between the "album" of images?

Not very experienced in python (nor Pi(s)), but something along the lines of:

• No longer calling delete image

• [Optional] Use a UUID for filename for multiple uploads

• Introducing an updater

import sched, time, random

def cycle_album(scheduler): 
    scheduler.enter(3600, 1, cycle_album, (scheduler,))
    updateEink(random.choice(UPLOAD_FOLDER, ORIENTATION,ADJUST_AR)

album_schedule = sched.scheduler(time.time, time.sleep)
album_schedule.enter(3600, 1, cycle_album, (album_schedule,))
album_schedule.run()
