get_serving_url via remote_api_shell.py

I want to record all the current urls for images I'm storing using appengine. However, when using appengine's remote_api_shell.py console, I'm unable to use the get_serving_url function even though I have PIL set up correctly on my local machine.

>>> c.image_blob
<google.appengine.ext.blobstore.blobstore.BlobInfo object at 0x16f0150>
>>> from google.appengine.api.images import get_serving_url
>>> get_serving_url(c.image_blob)
Traceback (most recent call last):

For now I just made a view to do the dirty work for me on appengine production machines, but I feel like there should be a way of calling the get_serving_url function via the console.

remote_api doesn't currently have a mapping for the get_serving_url API call. You can add it yourself by importing remote_api_services and adding it to the dict in the appropriate place, but either way you should definitely file a feature request.
