Sorry if this has been asked before.
I have several images. some that should have transparent backgrounds (but they show up white when uploaded to prezi) some with white backgrounds.
I have read this:
But the interface I see in advance editing on the website looks NOTHING like this?
Can anyone point out to me how to make a image background transparent as I am tearing my hair out trying to find out how to start this simple task
Thank you so much for your help!
