Apple has killed its Cards app for iPhone and iPad, introduced in 2011 to enable you to create and mail custom greeting cards for a fee. Cards has been removed from the App Store, and if you have it installed, the app will notify you that its associated service is no longer available. If you still want to mail cards, check out Bill Atkinson’s free PhotoCard app, which lets you email cards for free, or send them via postal mail for as little as $1.50. follow link
Removing Photos from iPhoto
Despite iPhoto's long history, many people continue to be confused about exactly what happens when you delete a photo. There are three possibilities.
If you delete a photo from an album, book, card, calendar, or saved slideshow, the photo is merely removed from that item and remains generally available in your iPhoto library.
If, however, you delete a photo while in Events or Photos view, that act moves the photo to iPhoto's Trash. It's still available, but...
If you then empty iPhoto's Trash, all photos in it will be deleted from the iPhoto library and from your hard disk.
