anybody help or advise. 
I have compiled a scene with text actor and 4 picture players & projectors. 
to show people what the scene looks like I have created a jpeg with the screen actor 
So can I (instead of having all the player, projector & text actors in this scene) which will be projected some 15 times during the performance  just put one picture player & one projector and
Point it to the jpeg I have just created 
Thanks
Arthur

 Ok, I think I got you wrong. The part of my answer, that makes sense to your question is:

If you used the 'capture stage to picture' actor, with a fresh unchanged projector actor, and nothing changed to the projection setup, the output should stay the same!

I'm not sure, if I get you right about what to achieve, but if you just want to play the jpgs you created, unrelated to the patch you created befor, you could just load the jpgs into the media list. Then you get rid of the everything but the projector (do a duplicate of the scene, just in case! Or even use a copy of your projectfile), put the picture player into the patch and connect it to the projector. You can then select the jpg with the media input of the picture player. If you did the screenshot with the 'capture stage to picture' actor, everything should be the same afterwards, as you use the same projector and it's settings.

If you want to have the picture switch on/off some more smoothly use a gate actor between player and projector or a button controller with values 0 and 100, connected to the projectors intensity value.
If you use a fader controller to the intensity instead/as well, you could even fade in and out. Or use an envelope actor for automation...
