I have an old house that I need to add big wall pictures, but nails and screws will not go in the wall. Any suggestions or advice

Lowes probably could show you a type of lag bolt to use

Try dynamite 🧨

Depending how heavy the pictures are, I've used self adhesive Velcro strips.

Drill a hole with a power drill and use plastic wall anchors that come with screws.

I have used gorilla hooks. They are pushed into the wall leaving a small hole. They have a hook that goes up into the wall. You can look into it.

Sheetrock... I think we use something called gorilla hooks which was kind of like an S and it holds a lot of weight

How would that work, there is chicken wire inside the lath board and plaster
