Can I recover photos from iPhoto?

Adding to the good guidance from Ijbrg...

Delete photos or recover deleted ones in Photos on Mac - Apple Support

Photos User Guide for Mac - Apple Support

The above is for individual photos in the current Photos app, and I believe the now discontinued iPhoto app behaved in the same fashion.

If you are asking about recovering the entire iPhoto Library, please provide more detail about the problem and users here will be happy to assist.

If you permanently deleted them (even from the „Recently deleted“ Folder) I don’t think there’s a way to get them back. If if they’re still in the Recently Deleted Folder then you can recover them.
