When you lock a picture, it cannot be moved or changed in any way. If you are editing pictures that have multiple elements, this function will be very useful to you.
In this article, we will teach you how to lock a picture in PowerPoint.
Locking an image
1. Right-click the image
2. On the dropdown options, click “lock”

3. Done!
Alternatively, you can also go to the “Selection Pane” under the Format menu, and then click on the lock button next to the corresponding image.
Unlocking an image
With locking covered, the next thing worth knowing is how to reverse it whenever you need to move or resize that picture again. Unlocking takes the same path as locking, just with the opposite menu option. Here are the steps:
1. Right-click the image
2. On the dropdown options, click “unlock”

3. Done!
Important note: This feature is currently only available in PowerPoint 2021. Older versions do not have this feature.
Conclusion
Locking is handy whether you are arranging an image made up of several pieces or simply guarding against a stray drag that nudges a photo out of place. With a few simple steps, you can keep your images looking exactly the way you want them to.
