I need to transfer photos from an iPad onto a computer, and I have access to a friend's Mac. The Apple website provides instructions here http://support.apple.com/kb/ht4083 however, it just says to connect the iPad to the Mac, and I have no idea how to do that. Can someone give me step-by-step instructions that do not assume any prior knowledge, e.g. I need to know how to connect the iPad to the Mac (Apple's instructions assume that newbies would know how to do that). Also, it is a friend's Mac, and I would prefer to have a simple way of transferring the photos, rather than using iTunes, since I would prefer not to meddle with my friend's iTunes settings for his own computer.
