I installed new ipad update software, then synced and now my photos wont sync.

I had loaded a lot of photos from a usb to my macbook pro iphoto albums.

I have restarted, resynced and even restored (and dumped the photo cache) and no help - any advice?

Have you selected the folder to sync your photos with in iTunes? I don't have a Mac, but it seems like: you uploaded pics to your Mac but haven't selected which photos to actually sync in iTunes.

When you connect the iPad to iTunes, one of the tabs along the top will be "Photos". Make sure you have checked the "Sync Photos" checkbox and indicated which photo folder you want to sync with.
