Seriously. Google owns these images and if you want to use them you have to give attribution and match their Terms of Service (read them here: https://developers.google.com/maps/terms). This is a personal / educational project.
Like I said, Don't use this to make big maps - it pretty much won't work. But if you want to try just clone the repo and then command line something like
php index.php 42.39506551565123 -71.16668701171875 42.32200108060305 -71.00326538085938 15 name
