Create a macro to delete ALL photos & videos from a Facebook group *MUST BE AVAILABLE TO START TODAY*

I need someone who knows the current facebook group structure (or are on facebook and can be added to my group as a moderator to learn the button sequence to delete media) to write macro commands so i can run a script to delete all the photos and videos in my facebook group that I own. I already had a free script that I used to delete all the posts but I cant find one to delete all the photos and videos so I need a freelancer to create one.
