How to set Files to show thumbnails without load a formal program to view the photos

If I am in the files program and want to view the photo thumbnails only some are show as pictures the rest are a standard icon (most). Can one set the Files program to generate all the thumbnails as a picture and not a standard icon.
As I have stated the Files directory program not a specific photo program.

Bye the bye I am talking the latest Fedora 36…

Have you tumbler installed?
