I transferred from MobileMe to iCloud.
Immediately iPad imported photos from my main computer. I turned Photostream off. Now the images are in the iPad and can't be removed. I have cleared Photostream on the main computer. Have returned to iPad and switched Photostraem back on - and also on main computer. But still the photos stubbornly can't be deleted. The delete button is greyed out.
By the way, am using Mountain Lion on a new iMac and it's an iPad2.
Any ideas?
