How do I resize an image on the server?

I am trying to use cfs:graphicsmagick on Windows, but it’s causing me problems: it can’t find GraphicsMagick, even though I can do “gm” from command prompt.

Besides, I am thinking GraphicsMagick is an overkill. I just need to make thumbnails. I don’t need it to be particularly efficient (yet).

There are plenty of packages to resize images on the client, has anyone written one for the server? Or do I just adapt one of these?
