So, netTrekker is a type of software that any school could use, meaning it could appear using a variety of IPs. So it's not checking links, it's telling the student the site is safe to visit. This particular student grabbed 4 of my images. That IP came from the University of Iowa. So in that instance the user agent is valid.
From now on, when I upload new images, their names will not allow for future image snatchers to find them easily. Thanks, Don, for a great idea.
