Trying to use iCloud /Photostream to get photos visible on my iPad 2. Using iPhoto 9.2.1(628) imported some ,photos from my camera and also dragged more photos from iPhoto to Photostream in source list at left. Nothing shows up on iMac Photostream page except in top RH corner "Uploading 654 photos". But nothing has happened. All the right boxes ticked in iCloud and iPhoto/photstream preferences and on iPad. So it seems to recognise what I am trying to do but will not do it. What am I doing wrong, how do I get out of it and is iCloud not quite as straightforward as Apple claim. Judging by the huge number queries about it one has to wonder if all is well with it.
I don't think you are doing anything wrong.. Sometimes Photo Stream needs a jump start.
On the iMac open System Preferences > iCloud
Deselect the box next to Photo Stream then reselect the box then restart your Mac.
On the iPad go to Settings > iCloud
Toggle Photo Stream off then back on then reset the iPad.
Hold the On/Off Sleep/Wake button and the Home button down at the same time for at least ten seconds, until the Apple logo appears.
