There are two main types of graphic file formats - vector and raster. Vector graphics use geometric shapes and lines and can be scaled without quality loss. Raster graphics use a grid of pixels and may lose quality with scaling. Common file formats include GIF, JPEG, PNG and BMP. GIF uses lossless compression while maintaining a limited color palette. PNG also uses lossless compression and supports transparency. Flickr is a popular photo sharing website that allows users to tag and organize photos in a "folksonomic" manner.
