# Requires Python and the requests and Pillow libraries.
# To run: python placer.py myimage.png 100 200 MyUsername MyPassword
# the first two numbers are the x and y coordinates for the image
#
# The script traverses each pixel in the image in a random order and
# attempts to place it on the canvas
