|silvertoolmanm, Go to that link and click on the "imgeditor.zip" file to download it, Save it to somewhere you can find it easily. Now double click that file to unzip it and expose the exe file and then double click the exe file to open it. I would the checkmark all of the 12 file extensions then click the "Repair associations" button.|
You could also right click on any jpg file, choose "Open With", select "Windows Picture and Fax Viewer", checkmark the small box (Always use the selected program etc.), click OK.
