How do you you lock a picture on word?

To lock a picture in Microsoft Word, right-click on the image and select "Wrap Text," then choose "In Front of Text" or "Behind Text." After that, right-click the image again, select "Size and Position," go to the "Position" tab, and check the box that says "Lock anchor." This will prevent the image from being moved inadvertently, allowing you to maintain its position within your document.
