Mass Image Cropping...

I actually was looking for something to do this for screengrabs. I just ended up using imagemagick that's built into my *nix boxes.

I wrote a command like this and then did a bash script to cycle over everything.

Code:

convert -size 300x300 the_original_file.jpg -thumbnail x200   -resize '200x<'   -resize 50% -gravity center -crop 100x100+0+0  +repage   new_file.jpg

basically turns the image into a 100x100 thumbnail cutting around the center.

For other stuff I've actually used what Ramster mentioned and it works great as well.

I did a little PHP script like that to basically do the same thing to quick build thumbs. Maximum crop size centered based on required thumb ratios. Also with auto-selection for default picture number to grab from gallery URLs.
