Copying on disk mounted as read-only is not possible. I have no experience with other file managers, but
MT Manager (as well as any decent filemanager with root privileges) allows user to (re)mount disks as RW or RO.
Simple alternative: you may just copy your sleeping image on /sdcard/suspend.jpg -- it has no influence on the power-off image, though.
