Are these sexual images?

Russell Blackford, writing for Talking Philosophy, has authored a post titled "No sexual images, please - we're atheists." Within the post, he discusses problems with designating something as a sexual image.

Here are two examples from two musical albums I really enjoy - both containing skeptical themes and challenges to religious belief. Are these sexual images? Please leave comments.

(1) Epica's full-length album "The Divine Conspiracy"

(2) Theatre of Tragedy's full-length album "Velvet Darkness They Fear"
