I can do that, but i want a script to do it cause i use bimp to process my photos and i just want to add a multiply layer to 100+ photos along with a couple of other things
Oh okay...
The plot thickens. I'm not a scriptwriter and in your initial post these other processes were not mentioned.
However you may be able to do this using the G'MIC command line tool. Unfortunately I don't know much about how to use this tool either.
I would recommend Graechan, who is among one of our top scriptwriters we're lucky to have here on Gimp Chat.
