I synced a few pictures from my MacBook to my iPad and want to delete some, only problem is I am traveling for a year and don't have access to my MacBook, can I delete them any other way or do I have to do it thru my MacBook?
If you do not have access to your MacBook, there is no good way to remove the pictures.
You could sync the iPad with another computer, but this is likely to cause other problems unless you are 'very' careful. Unless those pictures are a major nuisance, you're probably better off just ignoring them.
