[Web4lib] Optimizing graphics

[Matt Russell]

GIMP is a phenomenal tool, and great for all manner of image manipulation. 

For large batches of images that need to be resized, I use the 
imagemagick command line tools (http://www.imagemagick.org), and with 
these and a very simple 3-line script I can whip through a directory of 
200+ images and resize them as needed in short order.  Here's an example 
of the script that will resize pictures to 1000x700:
for i in *; do mogrify -resize 1000x700 $i; done

There are huge numbers of options, as you can see here:
