Here are some of my slideshows.
These were the old options before Google got rid of Picasa Web Albums: "You can view each slideshow in the small window provided, or you can click on the slideshow and bring it up in Picasa Web Albums. At that point you can run the slide show at a larger size, and have the option of using F11 to run (and exit from) full screen mode. I hope you enjoy the photos."
As the Picasa links fail, I'll try to just provide a simple link to the corresponding Google Photos Album. Take that link, then run a slideshow of the photos.
