I don’t know if it will give the kind of effect you want but you can use the Variation shader. And I don’t have the plugin but a bunch of planes under a Cloner is what I think you have.
Select all the materials for the planes in the material manager. That should show Material (x Elements) in the Attribute Manager. The Color tab should already be selected – the Texture slot should say <> click the arrow button to the left of that and choose Effects/Variation. That will put each separate image into a variation shader. Do a Render – the effects of the variation shader do not show in the viewport.
With all the materials still selected now click on the <> that will take you to the settings for the Variation (for all the materials at once). You can fool around with the settings in there to see if you can get something you need.
