When online, I need to upload some photos or artwork to my web page. But in Windows 10 I can not SEE any thumbnail view and I have to try and remember the name of the photo or graphic I want. 

That is on of the main reasons I still use Windows XP.  For  me, Windows 10 is a retro back to the days of console input. I can not see anything graphic. Maybe I am missing something. There must be some way to see a thumbnail view of all the files in my media directories. Right? 

So, my question is, how can a make Windows 10 into a real Graphical User Interface?
Specifically, How can I see a little thumbnail for each image in a directory?

I tried Google and all I got was a reference to Expression 2, which in not included in Windows 10. Or is it? 
EDIT This was found.

But I don't understand it.   
It depends on what dialog is being USED to display the files for upload.  For instance, if I use the file upload feature of this forum, I get the dialog shown below and can easily display images by selecting from the dialog settings.

In File Explorer, go to the folder with your images, then along the top menu of File, Home, Share etc, click View and pick one of the icon views.
is this what you were chasing?
