Have you seen this before and any ideas on a resolution. I have three devices Ipad, 5S and 4S and they are all doing exactly the same thing. In Itunes when I select Photo's to pick which photo's I would like to sync get a spinning indication that never stops as shown in Screen shot. Everything else is syncing normally. I reinstalled IOS. Removed and re-Installed Itunes. I tried something I saw on the apple site to delete the Ipod Photo folder and nothing so far has helped. Running IOS 7.1 and latest ITunes 1.1.5 and OSX 10.9.2. All my devices sync normally except for photos. I suspect it is something in Mavericks and have not yet tried re-installing. Been having this problem for at least six weeks.
