In just four easy steps we are going to show you how to disable the Picture Frame button on the lock screen of your iPad. With it enabled, anyone who picks up your iPad can begin viewing the photos stored on your iPad with the tap of a button--even if you have your iPad passcode protected.
1. Go into Settings, and tap on General. Scroll down and tap on Passcode Lock.
2. If you don't currently have your iPad passcode-protected, you will need to turn it on. If you do have your iPad passcode protected, go on to step 3.
Once you turn on the passcode, you will be prompted to enter a 4-digit numerical password which will be required to unlock your iPad. If you aren't comfortable with just a 4-digit passcode, you can turn off the Simple Passcode feature located on the same screen. This will allow you to enter a standard alphanumeric passcode.
3. Tap on the Picture Frame switch to turn off the Picture Frame (slideshow) feature on your iPad's lock screen.
4. That's it! Going forward you will no longer see the Picture Frame button on the lock screen of your iPad, thus protecting your personal pictures from anyone and everyone who gets ahold of your iPad.
