GIF Images
GIF images use a proprietary (patented) method for compressing images. The format
is a 256 colour palette based image format, making it suitable for drawn or computer
generated images. The amount of compression depends on the amount of detail in the
original image.
GIF images can also have transparent components and can also contain
multiple images to make animations. Transparency is dealt with later in this
tutorial.
The examples below demonstrate the overall compression that can be achieved
for a variety of image types. Each image is 200 pixels wide
by 300 pixel high.
