look at these cool GIF images.
These are the
same image saved with different background colours. The one to the
left has a dark
colour which, when placed on a page with a light background, gives
the image a rough
looking edge. The image to the right has a light (actually white)
background and blends in
nicely. If we
place the images on a dark background we get a reversed result.
As you can see
it is now the one saved with a light background that looks rough and ugly.
when saving images as GIF:s make sure you give them the same background
colour as the

common and popular is JPG or JPEG (Joint Pictures Expert Group). It

There is also
a third format which deserves to be mentioned here. I am referring to

colours as the JPG. Like the

also be made transparent. Surprisingly few web hosts supports this
great format but I
will change as it becomes more and more popular.
