The duplicated image will be placed at a little offset from the original image, as can be seen in Figure 3, below. Now, select the image on the slide and duplicate it by pressing the Ctrl + D keyboard shortcut.If the image cannot be selected and moved, then it is most likely a background image. How do you know that you are working with a full-slide image? If you can select and move the image on your slide, then you are using a full-slide image. The techniques explained in this tutorial will only work with full-slide images.Anything you expressly inserted on a slide and resized to fit the entire slide area is a full-slide image.Any full-slide images that live in the Slide Master or any Slide Layouts are background images.
