Sorry Tim, but that's a crock. Sure, judges should use reference but it's completely unnecessary. That reference is interpreted by that judge and for experience I know few judges that would interpret references the same. What the ideal judge has is consistency and that's the best you're going to get. Yiu don't need pictures to be consistent. Rick Carter knows what a deer looks like. Rick Krane knows what a fish looks like. Ken Walker know what a bear looks like. Tony Finazzo knows what a bird looks like. ANY GOOD JUDGE can give a thorough critique without reference pictures and all the reference in the world won't help a bad one.
