How do you put photos on the wall without ruining the paint?

To hang photos without damaging the paint, consider using adhesive strips or hooks designed for walls; these can hold weight without leaving residue. Alternatively, you can use picture frames with a backing that won't scratch the surface, or opt for removable wall adhesive putty. For a more traditional approach, use small nails or push pins in inconspicuous areas and fill any holes later if needed. Always test a small area first to ensure the method you choose won't harm the paint.
