How to send existing photos to photo stream? I just enabled iCloud on my iPad. I've also downloaded iPhoto on my Mac to sync my photos on the iPad. The problem is that I can only get pictures that I downloaded after I enabled iCloud on my iPad.

Is there a way to add all the photos to photo stream?
Drag the photos from the album to your photo stream. Careful though; I did this and can't find a way to undo what I've added to my photo stream!
