Sorry I don;t have a pic, but I use pegboard for the lid of one of my BP tanks. Granted, it does not allow light through, so you can't have a light from above with any good results. When I feed the occupant (Ashes) I rely on a light to the side of the tank.
I secure the lid with bungee cords, really tight. i do not remove them to take the lid up, but merely slide the lid to the left via a handle I screwed into the mid of the pegboard. I have to pry it up with a little screwdriver, but it is a good lid overall for retaining humidity.
