Where I can see photos in iTunes?

[iMore Question]

I'm adding more space to iCloud and want to save more photos there,but every time I want to enable it, it shows it wants to delete itunes photo which I can't see in order to decide weather to delete them or not. How can I see those photos? :-(

They are most likely in iCloud.
iCloud.com log in on computer.
