A picture frame is a decorative structure designed to hold and display photographs or artwork. Typically made from materials like wood, metal, or plastic, frames come in various sizes and styles to complement different types of images. They often include glass or acrylic to protect the picture from dust and damage. Frames can be found in homes, offices, and galleries, serving both functional and aesthetic purposes. They enhance the visual appeal of the image while providing a way to showcase memories or artistic expressions. Common types of frames include collage frames, shadow boxes, and floating frames.
