Retrieving photos from my passport

I discovered today that some of my photos from a trip to Ireland had been unintentionally deleted.  I attempted to look into my backup on My Passport from shortly after the trip to see if I could retrieve them.  They were stored in IPhoto.  When I attempt to look at the backed up image I get a warning about not opening IPhoto because it is a backup…so I discontinue my search.  I would like to find the lost images.  Can anyone help me with this?

Welcome to the WD Community.

What software where you using at the time that you did the backup?

Please note that most of the time you will need to use the same application that you used to create the backup.

What happens if you try to import the files using the iPhone interface? What are the extension of the pictures you are trying to recover? JPG? PNG?
