You can change the default app for jpeg files by going to Settings>Apps>Default Apps>Choose default apps by file type. You can choose the Organizer as a default app for jpegs although that is a little strange as a choice. If the file is not already in the Organizer, you will be given the option to import it into the Organizer catalog.
For scanning, it seems to me that a better choice would be to start off in the Organizer and then select Import>From scanner. That way the scanned image will be save to your hard drive and imported immediately into the Organizer.
I'm assuming you are using Win 10 and Elements 2019.
I thought of that – even tried it once - guess the newer Office or Windows 10 must be responsible because I had no problem when I had windows 7. Both the Elements and the scanner software are the same as I used on the old computer
Guess if I’m scanning several different pictures I have to do this each time.
