Weather satellite animated GIF for Raspberry Pi

# IMPORTANT! This Python script has one dependancy, simply paste this line into the terminal to install it!
# sudo apt-get install imagemagick -y
#
# Next, make a folder on your Raspberry pi:  /home/pi/pyscripts/wxgif/  (you probably have /home/pi/ already!)
# Save this script into that folder.
#
# WXGIF python3 script by Scott Hather - Run this every hour (using Crontab) and it will download the latest
# Weather satellite image of europe, then it grabs the latest 12 captured images and compiles them into
# an animated GIF for your viewing pleasure!
