A tweak to a particle setup

I've been following the "Eyeon Fusion Particle System Primer" tutorial on YouTube. The second half has a setup for creating a simple floating photo gallery using a pEmitter set to bitmap . However the tutor sets it up in a way that it isn't a continuous stream of particles - it animates only a set amount generated in in the fist few frames.
I'm trying to figure out how to work this same setup so that it will continually stream the bitmaps, but I need a little help.
I know there is a more complex tut where Image Planes are assigned to Background nodes, but the simplicity of this one makes it more attractive.
