A photo gallery is a collection of photographs displayed together, often in a physical or digital format. It serves as a way to showcase artistic works, personal memories, or specific themes. Galleries can be found in museums, art exhibitions, or online platforms, allowing viewers to appreciate and explore various images. In a digital photo gallery, users can easily navigate through images using a computer or mobile device. These galleries often include features like zooming, captions, and sharing options. Popular platforms for creating online galleries include Instagram, Flickr, and Google Photos, making it simple for anyone to curate and share their favorite pictures.
