Option one that’s a slideshow (and I can change how long it takes for each photo to cycle automatically). It automatically has thumbnails of all the photos at the bottom.
This is option 2 and called a carousel. I think it will always have the previous/next photos on the side of the one featured.
Option 3 is to do things in a grid pattern like this.
And Option 4 is below—they call it “stacked.”
