How do I make personal pictures fill up a slide proportionally and not have the white and gray background default? No picture uploads look pretty in the presentation...

  2. I make all our slides in Canva with a 16:9 ratio, save as a PNJ or JPEG, and upload as a background for the announcement slide in proclaim.

  3. That's PNG (viz., Portable Network Graphic).

  4. Haha. Yes. I didn’t realize I mixed up the letters. Thank for the catch.
