Using Python Scripting it would be a matter of a few lines. The only
drawback is that you'd have to change the script code for each
processing job you need to do in the batch.

I will post here the Python script needed to rotate each image in a
dir by 270 degrees and saving the result with an "R" appended to the

I apologize for the portuguese names inside the code - I had used
 this script as an example ina local forum.

You have to replace the line  "pdb.gimp_image_rotate (...)" for the
actions you need applied to the image (check what is available in the
GIMP Procedure Browser in the  Xtns menu). Offcourse, you also need
gimp-python  installed (it is tehre if you have a "python-fu" menu
entry. Else, it is usually available from Linux distros as a
separate package, or you have to give ./configure an
"--enable-python" option if you compile your own GIMP.

        tmp = arquivo.split(".")
        novo_nome = os.path.join (diretorio, tmp[0] + "R" + tmp[1])
        pdb.gimp_file_sabe (imagem, imagem.layers[0],
