Likely something about Exif info. When you take a picture on the side, most modern cameras note that in the metadata of the picture. I'm guessing we're getting multiple levels of things looking at that info, and each trying to do the right thing, ending up with the picture being turned too many times. But that's just a random guess.

Posted from my iPhone when traveling in the Centralia area.
Bellevue TESLA store thinks Burlington is going on line this coming Tuesday-Wednesday-Thursday. They were awaiting more information. They also think Centralia will be on line next week too. Nothing definite ... but said to keep checking with them.
Centralia crew said they were moving south to do another TESLA SCS installation as soon as they were done in Centralia. The crew doing the Burlington installation is another one of their crews as well.
