(cross post) Batch of two folders in...

Question

I have two folders with image sequences. I would like to run a batch of some sort, which opens one file from each folder, copies one of the images into a new layer of the other, then saves the results to a new folder, and continues.
Is this possible? How?

p.s. I am on Mac OSX Lion 10.7.2 with CS5

Answer 1

C. thanks again.
I found I can place the .jsx file into that scripts folder on my disk and then use "File > Scripts > Browse" to run it.
However, one image sequence is .png and the other is .tif, so will have to add some code, which I think I can do, to fix it.
Cheers
