I am not a programmer. I do not write scripts. All I want to do is take about 600 images (all the same size), and add an alpha channel to each one, and set the transparency color to each one. All images have the same color for the transparency color.
I've done this manually before, and it takes DAYS to do. I know that a batch function could do it in a minute or so. Gimp provides no usable help for creating a script to do this. Can someone help me?
