Oh.. As <http://bitworking.org/news/Sparklines_in_data_URIs_in_Python> shows, the reason I couldn't find a data: URI Python library is because they're utterly trivial to generate: import base64 import urllib raw_data = create_gif() uri = 'data:image/gif;base64,' + urllib.quote(base64.b64encode(raw_data)) (And it's even simpler if you leave out the base64-encoding.) -- -- http://mail.python.org/mailman/listinfo/python-list
