Funny Photographer: an alternative to Photo Booth

[mjgkramer]

I downloaded Funny Photographer and ran it. I guess I'm stupid, but I cannot figure out how to load a picture into the app. There is no open command and I tried unsuccessfully to drag a picture into it. There are no instructions with the app, Help is not available, and there is nothing on the programmer's web site explaining how to use it. I would appreciate your sharing with us how to load a picture.
