Run Win7 theme when locked

Let me start by apologize if this has already been asked but there are TOO many threads to go through.

My question is, is there a way to continue running the pics in your theme while the pc's locked?

If you click on an empty area of the Desktop and click Personalise then click Screensaver and set it to Pictures you could set your pics to run for as long as you want.

Make sure you tick the box to set a logon screen if anyone tries to move the mouse or stops the pics.
