Want jpg icons to show image thumbnails instead of generic icons

Hi:
Since updating to Windows 10, whenever I open file folders to view jpgs, the files' thumbnails are a generic blue mountain icon instead of thumbnails of the images themselves. How do I get the icons to go back to being thumbnail images again? Is there a command or menu option that will change this for all jpgs in my folders rather than having to change one by one?
Thanks!

Yes, thumbnail previews are enabled, at least it appears that way when I open the file folder. I can see the preview pane, but the preview is just a larger version of the generic icon. I imagine there must be a way to change this. I can't upload these images when I can't tell what they are. I use these images for my online shop and FB page. Obviously, I need a resolution to this so I can see what I'm uploading! Any other thoughts that might help?

Found the answer in another forum. thx.

Double check to make sure that you have thumbnail previews turned on.
