I got this working via File Explorer to send a copy of an image to a

But there is no "Send To" when I am surfing thru images in "Photo" or
"Photo Viewer".

Can this be inserted, or is there some other way?

The Metro "Photo" App doesn't seem to have a right-click context.

The Windows 7 style "Windows Photo Viewer" does have a context menu.
But it's not populated with Explorer Shellex stuff.

[W7 and W10 version of "Windows Photo Viewer" appear to be the same]

And I can't find any examples of anyone modifying it.

Windows Photo Viewer does have other controls.

There is a "Copy" option in the right-click menu.
