Can't sync my photos

[DickySan]

Hi,. im having trouble to sync my photos to my ipad. it was working properly before i switch my photos source from my pc to my laptop.
at first it works fine until error message came up in my ipad "you have sync high resolution pictured, please sync...etc"
it took me so long to backing up, so i switch off the auto sync and auto back up.
my music sync on my pc and laptop works just fine.
please help me to solve this problem. now i cant even open my previous photos.
