I can upload images to the Blobstore without any problems, but I've
had trouble retrieving and rendering them in my html template. I'm
using django-nonrel on appengine. I've tried to adapt django coding to
appengine, but being new to this I haven't had any success. My
relevant code is below. When I try to access the rendered broken
image's url I get the following error:
http://mackapp103.appspot.com/success/AMIfv94I_EVL2zU1gxCq7fqIr60veQfXulUagDaJnaGGdeupm5ioV6D8OzBKzcSiSIcDjd70et_6JE8wImOWYDzBm6Ua8sNfzink9bx6RqRUrtQPj9qnRA5kfGN4bKsboFsc3Cuk0-M2OsMWmMlccXIN9h9AMxrOAg/
Exception Type: BadKeyError
Exception Value:
Invalid string key

Any thoughts on how to fix this would be appreciated very much.
Thanks!
