With BIMP you can apply a set of GIMP manipulations on groups of images. Documentation @ http://www.alessandrofrancesconi.it/projects/bimp
BIMP can be easily installed on your Windows 32/64bit machine with the
official installer: https://github.com/alessandrofrancesconi/gimp-plugin-bimp/releases/latest/
then download gimp-plugin-bimp_win32.exe
Instead... to remove BIMP... if you really want... just go to GIMP's plugins directory and remove
bimp.exe and bimp-locale folder.
You must install libgimp2.0-dev and libpcre3-dev packages in order to have
the full set of libraries and dependences to compile BIMP (names can differ depending on the distro).
For Ubuntu / Linux Mint:
sudo apt-get install libgimp2.0-dev libpcre3-dev
Extract the archive containing the BIMP's sources and get into the extracted folder with cd. Then:
make && make install
Or:
make && sudo make install-admin
to make and install for every user in the system (needs root privileges).
There's no need to install or compile BIMP on Mac, because the default native build of GIMP for Mac OSX 10.8 made by Simone from http://gimp.lisanet.de/Website/Download.html already includes BIMP! (however, it's not guaranteed to be the very latest version)
