Hi - I'm a new GIMP user, and am trying to automate something without spending a whole paycheck on Photoshop!

Is this possible?

1. Resize image to pre-determined dimensions (number of pixels x and y)
2. Divide image into quarters and save the four separate image files. i.e. x/2 and y/2.

I have a bunch of images to do this for...

Yes it's possible.
1. What are the predetermined dimensions?
2. How do you want to name the 4 images to be saved?

Images all start at 7040x4640 pixels.

I would like the original filename with a suffix added to indicate which crop. Ideally the suffixes would be "NW" for the top-left, "NE" for the top-right, "SW" for the bottom-left, and "SE" for the bottom-right crop......however the suffix isn't that important as long as it's unique.

Here's a script to start
(unzip it and put it in your GIMP's /plug-ins/ folder. Restart GIMP.)

Just have an blank image with a blank layer opened.
Run script it'll be under Python-Fu/Quad Save...
choose input folder/directory where your jpg files are located.
chose output folder where the new jpg files will be saved.
Then OK to run script it'll open up each jpg file in the input folder scale them to your indicated dimensions,
select the quadrants and saves them as jpgs with NW,NE,SW,SE appended to file name before the extension .jpg.

Give a try and let me know if that works for you.

Looks like trandoductin gives the Gimp solution.

An alternative is using a command line application ImageMagick
http://imagemagick.org/script/download.php
down the bottom of the page for Windows installers.

Only two commands required so not worth writing a batch file. Note the mogrify command overwrites the files so work on copies.

split into quarters


or *.png depending on filetype

I'll try this weekend and let you know how it works.
