Lost Pictures updating from JB3.1.3 to iOS4 Question

[r5murphy]

Hi All,
I updated my JB 3.1.3 3GS to the new iOS4 and everything seemed to go ok my contacts were mapped over but my pictures didn't carry over to the phone. Where did I go wrong with the update. I restored as a new phone but it seems that the backup didn't map over my pictures.
Is there a way to get them back?

Thanks,
Rob
