Walls made of concrete and hard bricks do not take kindly to standard long picture hook pins.
Toly moulded hooks have short hardened steel pins pre-loaded. Hammer them into the hardest surfaces. They can usually be easily removed, leaving minimal marking.
Use cord, not wire. Do not use these hooks for heavy or valuable pictures.
