Note that if there’s a large number of files, the process might take a while, and if the search returns a huge number of photos, your system might even become unresponsive.
However, you can reopen the criteria window by clicking the gear icon and choosing Show Search Criteria. After you choose Save, the criteria will disappear from your screen, and you’ll only see the Smart Folder you just created. Remember to name it so that you’ll always know what it’s for – pick a name like Pictures Search or something similar. Do this for every picture format you can think of or for those stored on your Mac. Keep the Kind and Image options, but change the format. From it, select Kind, Image, and a picture format like JPEG or PNG. Click on it to add the criteria for the search.
