Description

The automated picture frame should:

• Cycle through a directory (folder) of pictures
• New pictures can be added by copying them to the picture directory (folder)
• Have a set of default operating parameters
• When the program starts, operating parameter changes may be read from the command line
  • change the default size of display window
  • change the default time a picture is displayed
  • change the default picture directory (folder)
• Scale pictures to the display window
• Cycle continuously through the pictures

Expand the Project's Requirements?

Multiple picture directories?
Make it a clock by displaying the system time (changing every second? 5 seconds? Minute? ...)
Add videos?
Add sounds? Beep when the picture changes?

Suggestions

Start by looking at the Python modules PIL, opencv, Ipython.Display, matplotlib, graphics.py, ... There must be something you can use in one of these (or other) modules.
