How can I use a sequence of images as a texture within a render scene? My scene contains a 'projector screen', and I wish to animate some other items, while changing the image that is shown on the screen. Currently, I'm using a plane with the image(s) used as an image texture. I am then manually rendering each frame individually and changing the image. Obviously this is a huge waste of time, so I was wondering how I could perform this in a more sensible manner?

Thanks!
Yes. Instead of using an image on the plain, use a series of images using the node setup shown. Add > Image, and then select your image series.

You can also texture a plane with a movie file. Movie Clip On Plane

Whichever way you go, frame rates must match...
