Picture handles
When you select the Picture Content tool and click a picture box that contains a picture, the picture displays with large circles for handles. These handles are called picture content handles.

Picture content handles display even if the selected picture exceeds the size of its box (see illustration above). The picture displays beyond the box boundary. You can crop the image by resizing the picture box.

If you want to move a picture box or see what its crop looks like without the transparent overlay, press the Command/Ctrl key. This temporarily dismissed the overlay and allows you to interact with the box as if the Item tool were selected.
