Photo Sharing from iTunes In iTunes, from the Advanced menu, I selected Photos to Share.  I then picked a folder and the hard drive cranked at full speed for good 5-10 minutes.

I do not see any of the photos on the iPad.  So, who did I actually share the Photos with?
Mathias is correct about the proper way to sync photos to your iPad. Sharing photos from iTunes approves them for Home Sharing, a system designed to share iTunes Store purchases and media amongst family members.

Home Sharing can also be used to allow access to photos from an AppleTV.
