This script works for me. don't forget to set the correct data source
folder.

img.save('./myoverview.png')
print 'Finished saving image'
# add coastlines to local image
cw = ContourWriter('/home/francis/FG-Docs/programming/python-msg/gshhg/')
cw.add_coastlines_to_file('./myoverview.png', europe, resolution='l',

print 'Finished adding coastlines'

Hope this helps
