While true, be advised that some consider it rude to hotlink images without permission
Edit: as pointed out below, Randall gives permission to hotlink/embed on each comic page.

It’s old internet etiquette. I think the point is that hotlinking asks someone else to serve content without giving them traffic, if that makes sense.
Does Randall putting “Image URL (for hotlinking/embedding)” directly below each comic on the xkcd site count as permission?
