Photostream is taking up a gigabit of space on my iPad's hard drive. I don't understand why this is. I thought on iDevices they were just in the cloud, but on a computer it saved to the hard drive. How do I free up this space?
I should clarify that these are not photos taken on the iPad, but rather on my phone. I tried deleting the photos, but I got a warning saying that deleting them would delete them from Photostream forever, which I don't want. Is there a way to stop it from storing local copies of photos in iCloud on my iPad?
