You could store the url in the datastore (after updating your model
definion to include the field :)
....
> frasi.gruppo = self.request.get('domain')
> frasi.link = blob_info.key()
frasi.servinglink = images.get_serving_url(frasi.link, 32)
> frasi.put()
.....
Then would just in the template
<img src="{{ elemento.servinglink }}" width="10%"/><br></a>
... or you could call get_serving_url in the code that renders the
template. You don't need a 'Serve' handler at all :)
