How do I delete photos from My Photo Stream?

You can delete photos from your photo stream the same way you delete other photos from your iOS device or Mac. Just select the photos you want to remove, and tap the trash can icon or click Delete. On your PC, select the photos you want to remove from your photo stream, right-click, and then select delete. When you delete a photo from Photo Stream on one device, iCloud will automatically delete it from the Photo Stream album or view on your other devices. Learn more about deleting photos.

Note: Deleting individual photos from Photo Stream is supported by iOS 5.1 or later, iPhoto 9.2.2 or later, Aperture 3.2.3 or later, and Apple TV Software Update 5.0 or later. You will need to manually delete photos you downloaded to iOS devices using iOS 5.0.1 or earlier after updating to iOS 5.1.

Make a temporary, backup copy (if you don't already have a backup copy) of the library and try the following:

1 - delete the iPhoto preference file, com.apple.iPhoto.plist, that resides in your

User/Home/Library/ Preferences folder.

2 - delete iPhoto's cache file, Cache.db, that is located in your

User/Home/Library/Caches/com.apple.iPhoto folder (Snow Leopard and Earlier).

or with Mt. Lion from the User/Library/Containers/com.apple.iPhoto/
Data/Library/Caches/com.apple.iPhoto folder

3 - launch iPhoto and try again.

NOTE: If you're moved your library from its default location in your Home/Pictures folder you will have to point iPhoto to its new location when you next open iPhoto by holding down the Option key when launching iPhoto. You'll also have to reset the iPhoto's various preferences.

NOTE 2: In Lion and Mountain Lion the Library folder is now invisible. To make it permanently visible enter the following in the Terminal application window: chflags nohidden ~/Library and hit the Enter button - 10.7: Un-hide the User Library folder.
