Teacher's Pet: DJ Inkers

I just got a new DJ Inkers CD, Animal Antics, and I love it!  I've already made two books for our science unit and have plans for more.  DJ Inkers has such a wonderful policy allowing teachers to use their images as long as they are credited and not for sale.  How great is a company that creates such cute, versatile clipart that teachers can use for their classrooms?  I use their images for my newsletters, classroom decorations, my classroom website, and much more!
