How I can control a second laptop for my primary laptop?

I'm trying to use an old HP as a Digital Photo frame. I be able to control it completely from my other two laptops, so you can change pictures and things remotely. Is it possible? If so, explain in as much detail as possible. I have remote access to the old now and I can put photos on the public record but I have to use the old lappy to set photos or make a slideshow. Old HP with Windows 7 new HP and Toshiba are still in Vista (which will soon catch up the two),

I use to try teamviewer.com this in almost all of my computers, its free for ever and u can transfer files from one computer to another. its fast, and you can change the look and set your own password to session at any time, or you can always have running so when ever ur computer or need, and only have one or the other ur, you can access it. is a great application and I recommend it. is large and never let me down.
