Syncing photos to iPad from iTunes

Question

I got my iMac in November 2009.  My iMac OS is the latest series 9.  My iPad2 was purchased in July 2011.  I figured out first sync of photos from an iPhoto album in December 2011.  That took a while.  It should have been easier.  Last night I decided to add some photos to the iPhoto album and sync to add some more photos to my iPad.  But iTunes does not seem to recognize the additions to the album.  In fact, iTunes has not picked up any events or new photos after 1/12/12.  And there were plenty of new photos uploaded from the camera to iPhoto on the iMac.  iPhoto says I have some 4250 pics.  iTunes only recognizes 4050. I tried deleting the iPod Photo Cache to no avail. I also noticed that when I show the iPhoto Library package contents there is a folder called "Originals".  Its last mod date was 1/12/12 (coincidence?) but there are uploaded folders by date within Originals that are dated after 1/12/12.  It just shouldn't be this hard to sync photos...it just shouldn't.  iPhoto, iTunes and OS are all updated. The only change I can think of is starting to use a new Lumix ZS8 camera.

Answer 1

First launch iPhoto with the Option+Command keys held down and rebuild your library with just the option to "Examine and repair iPhoto Library file permissions" checked.
If that doesn't solve the problem create a new album with the same photos, delete the old album and try to sync the new album with iTunes. See if that will jumpstart the syncing process.
