I'd like to know if Cisco supports multiple images on a 3750 on stack
if it's supported we'd like to load
ip services on the core switches (2 switches)and ip based on the remaining switches 4
if that is supported could you please provide a link that will show us how to do you upgrade of the images on the stack
I do not believe that it is supported to do what you suggest in running different images of members of the stack. In the stack all members must run the same image. If a switch is not running the same image as the master then the switch will not become an active member of the stack.
