Is there way to retrieve a photo that was deleted but still being used as Caller ID?

[mxtx816]

so i take a picture from my iphone camera and set this photo as the caller id photo for one of my contacts. my address book on my macbook syncs my contacts and now this photo appears in my address book too for this contact. i accidentally delete this photo from my iphone photo album before uploading it into iphoto on my macbook. but when i view the contact in my iphone the photo is still there, it still shows up when i get a call from this person, and the photo is still in my address book when i get emails from this contact. the problem is i still have no actual copy of this picture saved anywhere and im dying to save & back up this photo. obviously im happy its still associated with this contact but there must be a way to get this photo back somehow off the phone and saved somewhere either in the photo album or back onto my macbook... can someone PLEASE help! thanks!
