TOM: Hanging photos and artwork can be tricky, but a few simple tricks of the trade can help. Hi, I’m Tom Kraeutler. TOM: First, mark the spot where the picture will go, then choose between expansion anchors, which work best in thick solid walls, and hollow wall anchors, which are designed for thin or hollow material. LESLIE: If it’s drywall you’re working with, use a plastic anchor. And if the picture weighs more than 20 pounds, double-check the anchor’s weight limit to make sure it’s not exceeded.
