I've been using this to make thumbnails of jpeg files:

for img in *.JPG; do
echo thumbnailing $img
convert -geometry 105x70 $img $img
done

Are people supposed to know what OS/software
you're using that code with?


Linux/bash and ImageMagick, obviously :-P


That figures.

I wonder why you don't just extract the thumbnails
when possible. Don't your cameras create them in
the JPGs? It should be quicker and yield better
quality images.


To customize the size and quality, for instance.


Quality for thumbnails?
To what purpose?
It seems to be a waste of time, and a futile, unnecessary exercise.


No. I said "to customize the size and quality" which is different than
doing a quality thumbnail. ie, to have thumbnails of the exact quality
(small quality) that one wishes.
