Common Image formats on
the web Gif, Jpg and Bmp
|Image Formats-GIF, JPEG, BMP
When browsing the internet you are likely to come across many
different image formats. However, the most common formats are:
CompuServe GIF, JPEG, and Bitmaps.
|GIF stands for Graphic
Interchange Format and was standardized by CompuServe in 1987. The very
first GIF format was GIF87a and saves images at 8 pits-per-pixel with a
colour level of 256. Then in 1989 CompuServe updated the GIF format to
include animation, transparency, and interlacing, which was called
GIF89a. Apart from animation, transparency, and interlacing there is
little difference between to two.
The JPEG image format was developed by Joint Photographic Experts
Group. JPEG's best feature is the compression, you can compact the image
file to make it the size smaller (bytes). The problem with this format
is that there is a trade-off details detail and size. Generally its best
to save JPEG's at 50% compression.
Bitmaps was invented by Microsoft (everyone's favourite company). The
Bitmap format saves your image pixel for pixel, in other words, what
ever you see on the screen before you save is what you see when you open
the image again. The only drawback is that the file sizes can be
extremely large, which may result in longer download/upload times
