Question: I've got the Gimp for Mac OS X installed and working in my installation of Mac OS X 10.6.4. A very important tool I need is the David's Batch Processor plugin ( <http://members.ozemail.com.au/~hodsond/dbp.html> ) for batch auto-adjusting contrast/brightness/colour for my images.

There are no Mac specific instructions provided on the software's website saying how to install the python-based plugin. Can anyone please teach me how to install plugins for Gimp in Mac OS X?

Answer: 
You'll find the appropriate folders at `/Users/username/Library/Application Support/Gimp/`. There go in the scripts folder
and the presets go in the gimpressionist folder

I found these locations by looking at the GIMP preferences, and clicking on Scripts. The locations cited above were listed there.
There are OS X instructions in the [GIMP documentation](http://docs.gimp.org/en/gimp-scripting.html#gimp-plugins-install) and they suggest installing GIMP from fink or macports. Do this and you can follow the Linux/Unix instructions for plugin installation. Otherwise, the documentation states "good luck" if you install it some other way.

However, searching <http://gimper.net> suggests that, for a Python plugin, you should put it in: `[your home]/Library/Applications Support/Gimp/plug-ins` (create directory if necessary).
