  Graphics  Anything onthe page that is not actual text, from simple line to fully active image are graphics. There are many types of different graphics formats which one you use depends on many things.

  JPEG  The JPEG(Joint Photographic Experts Group) image files are a lossy format., although other operating systems may use JPEG. Nearly all digital cameras have the option to save images in JPEG format. The JPEG format supports 8-bit per color - red, green, and blue, for 24- bit total - and produces relatively small file sizes

  Lossy  A lossydata compression method is one where compressing data and then decompressing it retrieves data that may well be different from the original, but is "close enough" to be useful in some way. Lossy data compression is most commonly used to compress multimedia data (audio, video, still images) especially in applications, such as streaming media and internet telephone.

  Lossless data compression  Losslessdata compression is a class of data compression algorithms that allows the exact original data to be reconstructed from the compressed data. This can be contrasted to lossy data compression, which does not allow the exact original data to be reconstructed from the compressed data.  Lossless data compression is used in many applications. For example, it is used in the popular ZIP file format and in the Unix tool gzip.

  The TIFF (TaggedImage File Format)  Is a flexible image format that normally saves 16-bit per color - red, green and blue for a total of 48-bits - or 8-bit per color - red, green and blue for a total of 24-bits - and uses a filename extension of TIFF or TIF. TIFF's flexibility is both a feature and a curse, with no single reader capable of handling all the different varieties of TIFF files. TIFF can be lossy or lossless.. Some high-end digital cameras have the option to save images in the TIFF format.The TIFF image format is not widely supported by web browsers, and should not be used on the World Wide Web.

  The RAW imageformat  is a file option available on some digital cameras. It usually uses a lossless compression and produces file sizes much smaller than the TIFF format. Unfortunately, the RAW format is not standard among all camera manufacturers and some graphic programs and image editors may not accept the RAW format. The better graphic editors can read some manufacturer's RAW formats, and some (mostly higher-end) digital cameras also support saving images in the TIFF format directly. .

  The PNG (PortableNetwork Graphics) file format  is regarded and was made as the free and open- source successor to the GIF file format. The PNG file format supports true color (16 million colors) whereas the GIF file format only allows 256 colors. PNG excels when the image has large areas of uniform color. The lossless PNG format is best suited for editing pictures, and the lossy formats like JPG are best for final distribution of photographic-type images because of smaller file size. Many older browsers do not yet support the PNG file format, however with the release of Internet Explorer 7 all popular modern browsers fully support PNG. The Adam7-interlacing allows an early preview even when only a small percentage of the data of the image has been transmitted.

  GIF (Graphic Interchange Format) Islimited to an 8-bit palette, or 256 colors. This makes the GIF format suitable for storing graphics with relatively few colors such as simple diagrams, shapes and cartoon style images. The GIF format supports animation and is still widely used to provide image animation effects. It also uses a lossless.

  The BMP (bitmapped) format  is used internally in the Microsoft Windows operating system to handle graphics images. These files are typically not compressed resulting in large files. The main advantage of BMP files is their wide acceptance, simplicity, and use in Windows programs.
