""" Returns thumbnail URL and create it if not already exists.
.. note:: requires PIL_,
if PIL_ is not found or thumbnail can not be created returns original URL.

Usage::
{{ url|thumbnail:"width=10,height=20" }}
{{ url|thumbnail:"width=10" }}
{{ url|thumbnail:"height=20" }}
Parameters:
width
requested image width
height
requested image height
Image is **proportionally** resized to dimension which is no greather than ``width x height``.
Thumbnail file is saved in the same location as the original image
and his name is constructed like this::
%(dirname)s/%(basename)s_t[_w%(width)d][_h%(height)d].%(extension)s
or if only a width is requested (to be compatibile with admin interface)::
%(dirname)s/%(basename)s_t%(width)d.%(extension)s
