To create the cropped image into the background of the slide, right click on it and select Send to Back . You can then have the text dialog appear at the top of the image. Make sure there is enough contrast between the text and the background image so anyone can easily read them.
In addition, users can reduce the size of the presentation by using PowerPoint's Compress Media option: Select File → Info → Compress Media and choose one of the three quality options given.
