Research all image file types...

 Jpeg file....
 a JPEG is a compressed image file format. JPEG images are not limited to a certain amount of color, like GIF images are. Therefore, the JPEG format is best for compressing photographic images. So if you see a large, colorful image on the Web, it is most likely a JPEG file.

  If the image is compressed too much, the graphics become noticeably "blocky" and some of the detail is lost. Like GIFs, JPEGs are crossplatform, meaning the same file will look the same on both a Mac and PC.














Gif File....
  GIF files are a format commonly used for graphics presented on websites. GIFs can contain a maximum of 256 colors, and are therefore best for images that contain simple shapes, a limited color palette, text and other elements as opposed to photos. GIF stands for Graphics Interchange Format.
 

BMP file...

BMP is one of a number of file formats used to store digital images. The bmp format was developed by Microsoft for Windows and all programs created for use in the Windows environment will recognize .bmp image files. The BMP file is a bitmap file which produces images from hundreds of small pixels of color. Little dots of different colors when combined together will produce the image which can easily be loaded from most web sites.



PNG file....

Image file stored in the Portable Network Graphic (PNG) format; contains a bitmap of indexed colors and uses lossless compression, similar to a .GIF file but without copyright limitations; commonly used to store graphics for Web images.
The PNG format was created in response to limitations with the GIF format, primarily to increase color support and to provide an image format without a patent license.




TIFF File...
TIFF file formats are used for storing very large, high quality images. TIFF is the favored image format in many graphic applications. These include image manipulation programs, desktop publishing and 3-D imaging applications. Other applications that use TIFF is optical recognition software and scanning and faxing applications. A TIFF version called GeoTIFF is used to store geo-referenced raster imagery.

 

WMF file...
WMF files have largely been replaced by more standard formats, such as .JPG and .GIF images. The WMF format is still supported by various programs, including Microsoft's Windows Photo Viewer, which is included in Windows 7.

 


EMF file...

Windows vector graphics format recognized by many image-editing applications; basically a 32-bit version of the original Windows Metafile Format (.WMF), which only supports 16-bit data; saves image data in an RGB format and does not support CMYK data.
EMF can also used as a graphics language for printer drivers.
