How do I get rid of the moving preview photos in my iphone photo albums?

I have an iphone 14 pro with iOS 18.2. When I go to photos and open one of my albums, how do I get rid of the large preview screen and only have the thumbnail shots. If I can't get rid of the preview, then how can I stop it from rotating through all the photos in the album? I think that feature is totally useless. I don't want my photos to play like a powerpoint movie everytime I open an album.
