Photo Thumbnails just Icons in Dell Mobile Connect Windows 10

Hi,

Dell Mobile Connect used to show actual photo thumbnails in the Files Pane.

I have Photoshop and changed the default for JPGs to Photoshop.

Now Dell Mobile Connect just displays the Photoshop "Ps" icon instead of a photo thumbnail!??

I changed the default to Windows 10 "Photos" app as the default for JPGs.

Now I get the Mountain Scene Icon instead of pictures!!?

HOW do I get pictures displayed in the Files panel? What should I set the default viewer to, so it will display pictures?

Thanks
