I wondered myself and looked it up.

It's the __str__ method of the image class which returns the tag.
Additionally, there's an index_html method defined which returns the 
file itself.
No __call__ method though. This is something I always are confused of, 
why sometimes __call__() is used, and sometimes index_html().
