It’s easy to turn photo stream on or off in iOS. The following steps assume that you are logged in to your iCloud account on your iPad, iPhone, or iPod Touch.
1. First of all, open the Settings app.
2. Next, scroll down to the photos settings and tap that.
3. Finally, tap the on/off toggle switch for “photo stream” or “my photo stream.”
The steps are the same whether you are using the smaller iPhone and iPod Touch or the larger iPad and iPad Mini. It does look a little different on the iPad and iPad Mini.
