Raster graphics are bitmap images, which means they're basically grids of individually defined pixels (as opposed to vector graphics, which produce images using mathematically generated points and lines). The dominant web graphics formats, GIF and JPEG, are raster graphics. Raster is often used with complex images, such as photographs.
