FYI,
urls = ("/([\w\.-_]{3,100})", "Resize")
allows for *.jpeg, *.tiff, *.gif.gz, *.jpg.bz2, ...
Use `mimetypes` (given the filename) or `PIL` (given the file) to determine
the extension, type, etc.
>>> import mimetypes
>>> mimetypes.guess_type('image.jpg')
('image/jpeg', None)
>>> mimetypes.guess_type('image.png.bz2')
('image/png', 'bzip2')
