Should be trivial to set up something like that if you’ve got parts you want to work with. Any desktop with an automatic background switcher should be able to cycle through images in a directory you specify on a timer. Set up your favorite remote access software (SSH, Samba, NFS …) and you’re done. If you want more control over the behavior, you could script up something custom with a little more effort – but it’s still not particularly hard to implement something like that.
Watch out for burn in on the screen if you’re leaving it on all the time.
