Ipod will not Sync with photos

I have been trying to add photos to my 2gb 2nd Gen Ipod Nano for about a week now. I try to sync the photos using itunes by clicking on the photos tab but it always comes up errors. my ipod will only sync music and after its done being synced it automatically disconnects itself. It will not even let me restore it. I think it might be because I took of enable disk use, but now every time I try to put it back on my ipod wont do it. Please help.
