size of slide shows

Disregard my last response to leonie. Here is my new response.

I think I just discovered what you are telling me. I open an album on Photos and right click on play slideshow. The slide show begins playing in a small scale. Than If I click on a theme as you suggest and than click again play slideshow the slideshow begins full size in that theme. Problem Solved. Thank you for your help

I open an album on Photos and right click on play slideshow. The slide show begins and plays the entire album but in small scale. before starting the slide show I can enlarge any photo by double clicking it. I can than scroll through the entire album and they will all be full scale. But if I want to watch the album in a slideshow even after I have enlarged the first picture the slide show still plays in small scale.
