Am I missing something or can we really not post to Instagram directly from SkyDrive? Does the photo have to be stored on the phone?

On the Nexus 5 you can post photos that are uploaded to Google Drive.

Well, I'm not sure which version of instagram you're using, but on 6tag, if you click the import button (I can't remember the name, but its to the right of the default camera button) and go to the SkyDrive album, it should be there.

I'm using the official Instagram. I was surprised at this omission.

Its still a beta. By the time its official, it'll probably be there. I'd recommend using 6tag until it becomes official.
