Hi all

I'm trying to make an animation of photographs falling.
I've built a simple NURBS plane and instanced the geometry to a particle system with gravity.
I have the photo images named sequentially, and was planning to connect a movie node to the colour channel of the particle's shader, and use an expression to link the image sequence number to the particle number.
Not sure how to do the expression though - can anyone help (or offer an alternative idea)?

thanks
