Here was Zenescope’s official statement on the question of using Shannon Doherty’s likeness in the Charmed comic.
“Unfortunately Ms. Doherty has declined to be involved in the comic version of Charmed. This includes the use of her likeness. We had hoped that she would allow us to use her image and that we would be able to bring her into the Charmed comic book exactly as she was in the show but at this point that has become impossible. While Ms. Doherty’s likeness will not be used for the character we are still very excited about the direction we are going with Prue and we hope that fans of Charmed will feel the same way.”
