I'm afraid I'm not very wised up technically. I have taken pics on my ipad. They have synced to my pc, in the icloud photostream, where I can view them. I want to attach some of them to an email, using my normal email service. Can I do that?
You can view them in iPhoto !
In the left column there should be an item "Photostream" if you synced your account with the iCloud account.
