Thanks Augeas for clarifying. I also did a deep scan, but same result. It found a lot of png files, and old jpg files where I could see the preview, but the new ones seem to be lost forever.
Would be nice if Windows dedicated a special folder for deleted files from the recycle bin within a week. One normally finds out the mistake in that time span.
But I am a little wiser now, and not so trigger happy in the future
