Correct photo orientation when uploading from iPhone?

Question

iPhone

When uploading a photo to the site and then displaying it, the picture turns out to be rotated.
When we take a photo, holding the iphone in this way: cnet3.cbsistatic.com/hub/i/r/2012/09/17/314619ad-8... the photo turns to one side.
and when you hold the iphone, when the main button is on the side of the right hand, u.yablyk.com/2014/01/iphone-beach.jpg
then the correct orientation of the photo is obtained when loading.
Moreover, if you do this through android, everything loads normally, even if you keep the android upside down.
Who will advise what?

Answer 1

In general, read this (not) nonsense as an option and make a crutch based on this:
if user.device == apple

Wait for the release of iOS Nn with a new, revolutionary feature to automatically rotate the image to the correct orientation

Because you need to go to the Camera Roll on your iPhone, select the desired photo, click "edit" and move it the way you want :)
