Hey Frank, It appears the URLs are indeed going stale if 404's are served. Generally, the pattern is meant to be used to generate a serving URL on the fly. You could write up a quick request handler which receives a request for the image, uses its blobkey to generate a serving URL, then sends a 302 redirect response to that URL, which would resolve the issue.
Let me know if you have any further questions on top of this, I'll be happy to help.
