Automated merging and export

Nothing Gimp I know of off-the-shelf: Maybe someone will come up with one. Otherwise it is write your own script and one of the clever guys might give advice.

However for batch operations ImageMagick is better. https://imagemagick.org It is command line and you will need to include the commands in a Windows batch file with a variable for the individual images. Use png's rather than .xcf

For example: To add the 'variable' image to a fixed bottom layer

Code:

composite -gravity Center 01.png bg.png temp.png

Then add the 'top' layer to the previous combined layer essentially the same command

Code:

composite -gravity Center logo.png temp.png 01-combined.png

and delete the temporary file

Code:

del temp.png

That sequence gives this. https://i.imgur.com/FCmomWj.jpg
