craigslist.org seems to do this when you upload pictures of the item
you're selling. I'm not sure how they do it, but I imagine they use the
mogrify command from imagemagick:
mogrify -resize 800x600 somefile.jpg
This will overwrite the original somefile.jpg with an 800x600 version of
somefile.jpg
This gets tricky, because what if the original is taller than it is
wide? The above command will distort the image.
You can also:
mogrify -resize 30% somefile.jpg
This gives you the correct aspect ratio every time, but what if the
original image was already small?
Anyway, some food for thought.
