Goal

Particles density produced by Texture Image Sequences such as black and white.

Current Situation

Unreliable Failed results.

Question

Below particles correspond to Black and White, if I take manual intervention by clicking say ramp on .... ramp off repeatedly, the usual incantations. I have never achieved a successful render of an image sequence. Single Image I can achieve as in the below pic.

Has anyone achieved reliable results with the above goal and if so how?

If I understand you correctly (and I might not) and you want to control particle emission with an image sequence, then this isn't possible. Only the first image in an image sequence will be taken into account for particle density.

According to Brecht, one of the Blender developers here:

The problem here is a limitation of the particle system. The way it works is that a distribution of particles is generated once beforehand (to have an even distribution), and can't be dynamically changed.
