Yes, more than 1,000,000 images! You can get it in a steady stream via the The Mechanical Curator, a Tumblr blog which hourly posts randomly selected small illustrations and ornamentations. Or you can dive into their Flickr photo-ocean — I know that Flickr calls it a photostream, but in this case it's an ocean. It's organized by album (e.g., musical instruments, architecture, children's books, cycling, technology, ships ...).
The search function is not as helpful as it could be -- keywords such as "batarde", "manuscript book", and "Netherlands" failed to turn up this image. I found it, instead, by scrolling through the album entitled "Images Online: a selection".
Still, what an incredible resource!
