A picture frame is a protective and decorative structure that holds and displays photographs or artwork. Typically made from materials like wood, metal, or plastic, frames come in various sizes and styles to suit different tastes and settings. They often include glass or acrylic to shield the image from dust and damage. Frames can be found in homes, offices, and galleries, enhancing the visual appeal of the displayed images. Some frames are designed for specific occasions, such as wedding or graduation frames, while others are more general. They can be hung on walls or placed on surfaces like tables and shelves.
