I get an error from your monster palette ref. https://cdn.discordapp.com/attachments/499070278366789632/786822757299519518/rgb-32-64-4.gpl  Can't try it out.

Nothing straightforward that I can find.  There might be a dedicated Gimp plugin around, can't find one.

Easier in linux than Windows. You need Python installed to run this script.
https://gist.github.com/mePy2/bb2f6f63af3f352378574ad1231555f5

And other scripts / plugins used as well Goes like this

Extract the palette to text using Gimp.  https://i.imgur.com/YtkDh6g.jpg

The python script uses the default text file name.  Looks like this: https://i.imgur.com/6MJ5UfR.jpg
That produces a 1 pix x number of colours png file
Put in some spaced guides ( I use a script for this)
Split into layers using the guides (I use a plugin for this)
Resize the canvas size to suit
Space the layers out using the align tool.

Quote: Does this mean to put the .py file and palette.txt in the same folder? Also, I assume from the GitHub account's name that this script is meant to be used for Python 2?

I assumed python 2.7 Everything in one folder, that is the easiest way, saves some long paths.

A bit of  spare time yesterday, so a try out in a Win10 (VM) to check that it works there. For anyone interested.

First installed python from  https://www.python.org/ftp/python/2.7.8/python-2.7.8.amd64.msi  (all users, default location C:\Python27 )
Next PIL from https://pypi.python.org/packages/2.7/P/Pillow/Pillow-2.5.3.win-amd64-py2.7.exe

Get a palette.txt file from Gimp
script palette_generator.py and palette.txt in the python folder
Run from there to generate palette.png   screenshot: https://i.imgur.com/Kmec5yu.jpg

How i can add colormap in batch to multiple image/layers ?
i've tried BIMP but doesn't support Colormap plugin.
After Colormap i have simply to output same set of images.
Thank you

• Open one layer on convert to indexed to generate the colormap (or force the color map with a palette)
  
• File ➤ Open as layers the other layers (the dialog lets you select multiple files at once), they will be automatically converted to use the colormap of the image
  
• Use a script such as my own ofn-export-layers to export the layers to individual files.

Possibly (untested)

Ofnut Reply! Great!
There is a way to mantain filename when importing as layer? so i can export filename as well with your Export-layers
thank you
