UPDATE:The link changed at some point in the last year. (Which means that all the images I had used are now broken. Oh well.) Here is the link.
Last week I mentioned a site that had free pictures for your use, today I stumbled across a great site with woodcuts of various biblical stories, free for your use.
These woodcut illustrations by Julius Schnoor von Carolsfeld were originally printed in “Das Buch der Bücher in Bilden.” They were scanned by Publications for Latin America, WELS.
