How do I make all of my pictures open full screen?

Hello,

When I open a picture on my Microsoft Surface Windows 10, sometimes it opens full screen and that's the way I like it.

However, sometimes the JPG image opens up small and I have to use the 'zoom' functions to enlarge it to full screen.

I would always like my JPG photos to open up full screen.  Is there any option available to select where I can have the photos open up full screen automatically?

Thanks in advance for any assistance you can provide.
