1. How to Open Images on Preview

Preview is Mac’s default image viewer, so when you double-click an image on your Mac OS Mojave, it opens automatically in Preview. And if your default image file association settings has been changed, you can view images with Preview by Command-clicking or right-clicking an image file, and then scrolling to "Open with" and then choosing Preview.

To open a file directly from the window of Preview app itself, select the Preview app from the Application folder or Launchpad. Tap "File" on the menu bar of the open Preview window, and then select “New” and choose the desired image file.
