You can wrap text around pictures to prevent overlap.
Create a text box and a picture.

Position them so that they overlap each other, and then group the text box and picture together.

Now that the text box and picture have been grouped together, any text that had been obscured behind the picture is now wrapped around the picture instead.

You can change the display priority of the Text object and Picture object and still maintain the group.
You can cancel the wrapping feature so that the text is displayed on top of the Picture object.
