You can do the same in one line using find with mogrify:
find -iname "*.jpg" -exec mogrify -resize 50% {} \;
This will resize all jpg images in the current directory and in the tree
below it. mogrify is just the same as convert, but it overwrites the
original file. No need to do that in two steps (convert + mv)
