Creating a Display Copy preserves your original-quality image in the file system and tells Mylio Photos to show the edited version instead of the original, unedited version.
From the external application, use the Export or Save As command to create a JPG or TIFF and append
_displayto the file name (i.e., photo1.jpg would become photo1_display.jpg).Save this file to the same folder as the original file. Mylio Photos will stack the Display Copy with the Original and display the edited version in your Mylio Photos Library.
