The issue is that the place what you want to mask will be different each
time. Depending of the amount of screenshots, it might be easier to do it
one by one. Select the part you want to keep enhanced, reverse your
selection and then use the bucket in gimp to fill the rest with a mask
I am sure you could make GIMP do it in a much easier way so that you only
need to select and the rest happens automagically.
What I do if I want to edit a lot of images (several hunred) I use a loop
like: for I in *.jpg;do gimp $I;done
Disadvanatage is that you need to close gimp after each time and it
If the place that you want to mask is at the same place each time, you
could look at ImageMagick which is pretty good for editing images from the
prompt. Much faster.
