I started with a Google Earth view of a building. I am adding triangles to the image to represent video camera views.

I am accidentally grabbing the image and moving it away from the triangles I added. I then have to move the original image carefully back under the triangles to realign them so I can add the next shape or text box.

How can I save the shapes to the original image of the building so they stay as one image and will not move independently?
