Right! And while you're at it, stop assuming that percent signs have

But those would be silly.
Some special syntax is known about: | < and > for example. % less so
(I've never, ever used it in live input AFAIK).

You've never used ImageMagick?
If you want to shrink an image to half its size:
convert dragon.gif -resize 50% half_dragon.gif
