Answer 4

In addition to what bharath508 said,
.jpg - typically compressed and useful for photographs (high-quality and low-size)
.gif - low size, transparency, and animation (but often poor quality); useful for low-quality animations
.png - often compressed; transparency and also useful for embedding metadata for future editing (e.g. Adobe Fireworks); useful in web graphics (e.g. buttons, tiled backgrounds, etc.)
.bmp and .tiff - not useful on the web, but sometimes used for lossless saving
.svg and .ai - vector graphics for high-quality, scalable vector art work; useful for symbols and graphics (e.g. text, map outlines, flow charts, etc.); not supported by all browsers
