The Special menu lets you preview image files so that you can quickly browse pictures on your computer. You can preview raw, JPEG, TIFF, PSD, PNG, GIF files, and any other image file that can be previewed with Quick Look.
To preview an image file, simply select it in the Special menu. If you do not see previews, you may have disabled them. To re-enable them, select the “Show previews in the Special menu” checkbox in the Previews pane of Application Wizard Settings (macOS 13 or later) or Application Wizard Preferences (macOS 12 or 11).
