Sorry for late reply to this,
Correct me if i getting wrong your meaning, did you mean your old stream the image file can't appear or when you post a new stream?
Because i have tested post a new stream that is work -> http://screencast.com/t/6DGrXXYIB
If you're mentioned about the old stream, did you have another user account which having the image in the old stream so we can try investigate on this issues? Please advise.
There seems to be an issue with our CDN (CloudFlare) - have opened a ticket with them - researching now. Will advise (some users see images, others do not)
