Vector images are defined mathematically and can be easily scaled without loss of quality, while bitmap images use a grid of pixels of set colors. GIF files are suited for simple images like graphics or logos, while JPEG is suited for photos due to relatively small file size, though quality decreases with repeated editing. Embedded graphics are permanently part of a file, while linked graphics depend on the source file. A color palette is a set of colors used in an image. Lossless compression compresses files without quality loss, unlike JPEG. PNG uses lossless compression and overcomes GIF and JPEG limitations but does not support animations. BMP files cannot be compressed so have large sizes and limited support. Flickr is a photo sharing website used
