IOS 6 won't download all my photos

IOS 6 I just did my update on it and it will only sync 227 photos of my 788 when I absolutely KNOW that I HAVE ENOUGH SPACE ON MY IPOD FOR THEM!!!!!!! This is SOOOOOOOO FRUSTRAITING!!!!!! HELP!!!!!!!!!!!!!

-4th generation

-IOS6

-Windows PC

-The newest updated ITunes that's out

-8GB with ENOUGH SPACE ON IT FOR MY PICS!!

Also after I sync it, it says 517 items could not be synced. See iTunes for more information. What the heck is that about???
