Yearbook

The Eye line is the space that in between 2 or more photos.  What it is used for really is so that you can see the changes perhaps and pr the differences between photos, when referring to a yearbook the eye lines would be the spaces on the edges of the inside Im inferring.
Body copy is the text part of the AD, so in the lines between the paragraph you leave some spaces in between to differ from one to another.

This picture is the great example of both words because as you can see in the pictures the photos have some spaces on the edges, and although they are close but not too close so the can overlap and differ and mainly just pop up. As for the body copy is also a good example because it has the lines and the spaces of each paragraph and line so they can show and differ as well.
