I had several albums of photos on the iPad. I created a new (additionanl) folder/album in My Pictures, opened iTunes, chose the new album (only the new album) from the checklist of albums to sync.
This action loaded the new album on the iPad and wiped out the others.
Do I need to checkmark and re-sync EVERY existing album when I add a new album of photos?
In other words, I have an album "A", and album "B", and album "C" on the iPad. I want to augment these with album "D". Do I need to checkmark and resync A, B, and C just to add D?
