Your linux shell thinks it is running a shell script (from is not a
valid command in bash).

To execute this script with the python interpreter type (from a shell

python image-harvester.py http://some.url.whatever/images_page

Read the comments at the beginning of the script and you will discover
all sorts of important usage information.
