Multiple pictures resize
When you need resize huge quantity if pictures this script coud be useful :)
run it in directory with pictures, and all pictures wit the mask *.JPG will be resized in the directory you specified.

for k in $(ls *.JPG); do convert $k -resize 800 -quality 90 3/new-$k.jpg; done
