How to either simultaneously delete photo from photo stream and all devices; or how to designate a photo not to go to the cloud at all.  I'll do something like take a picture of an item at Costco to look it up on the net later.  But I don't want the picture bumped to the cloud, then to my Mac and pad.  It's going to be deleted once it's done it's job.  As it is, I have to delete from my phone, the cloud, the mac and the pad, which gets old.  Or simply leaving them there cluttering up my photos collection.
Turn off the automatic stream button for streaming file from cloud to Mac and iPad, this may work.
