Delete photo with exclamation mark in black triangle.

Is there a fast way of doing this?

No, not in iPhoto. Aperture can search for photos with missing original image files, but iPhoto not.

It would have been quicker to do the deletion from inside iPhoto. Then the original image files, the Faces, the Previews, and the thumbnails in iPhoto would have been deleted together. Delete all thumbnails with the exclamation point from the Finder, or restore the previous version of your iPhoto Library from your backup, and then delete the Photos using iPhoto.

No

You destroyed your iPhoto library by changing it using the finder - you must never do that

Now you must either restore your backup from before you made this error and delete using iphoto

or put every thing back exactly as it was or delete the photos one by one using iphoto a you should have to begin with

or use iPhoto Library Manager to rebuild your library without those photos and without projects and slideshows

or just start over with you original photos

In my case, I don't remember if I deleted photos from 'Finder'. I can see the photos in the event but if I want to open them, an exclamation mark in a triangle appears.

I want to recovery these pictures.

My last backup was few monts ago and the photos are not there... 😟

What can I do?

Then all you've left are the thumbnails you are seeing in the events. Make sure, you save at least those before they are lost too. Select all all photos in an event and drag them to a folder on the Desktop. That should export the thumbnails you are seeing as a JPEG file.

If the photos have been missing for more than a month, even expensive data recovery software will not be able to restore your photos, if you have used the computer since the photos vanished.

Thank you, I went in the thumbnails folder for copy the photos. It's smaller but I have the photos back!
