deleting from photo stream?
I have read many of the threads like this. Some of them just say: yes, you can do it, but do not give instructions. Others say you can only do it by reseting or deleting a photo stream.
The photos were taken on my iPhone. I have deleted them from there, but my photo stream on my iMac's iPhoto still shows them. I have tried selecting them in photo stream on iPhoto and using the delete key. All I get is a beep. They won't drag to the trash can.
I am using iPhoto '11 (9.2.1). Some instructions say select iCloud from the source list, but iCloud is not in the list.
What am I missing? How do I delete the photos from everywhere in the system of my Mac's, iPhone and iCloud?
Thanks in advance for your help.
iMac (27-inch Mid 2011), Mac OS X (10.7.5)
