Save new graphics
(those you've just scanned in or downloaded from your digital camera)
as .tif files to store them in the best possible
condition for later use. Then when you prepare them for use on a
webpage, convert them to .gif files if you intend
to make the background transparent (invisible) or if they contain
text or large plain areas that would be blurred as .jpg files. Otherwise,
convert them to .jpg files, which utilize the maximum
amount of colors while condensing them for faster loading. Note
that .jpg files deteriorate every time they are opened in a graphics
program and re-saved. The deterioration especially shows up in small,
plain text and areas of flat color.
shadows, first determine the color that will serve as the background
of the page where the image will be used. Take note of the RGB
numbers of this background color, then use those numbers to create
the same color for the background of the image before
adding the shadows. Otherwise, the shadow will contain a color
that does not blend in with the background of the page.

The smallest screen is 640 pixels wide (although WebTV, which
uses television screens, are narrower, about 550 pixels wide)
and the largest is 1600 pixels wide. A good rule of thumb is to
make your background image 1200 pixels wide for the most commonly
used screen resolutions.

like <img src="graphic.gif">.
Do not use the image by linking your webpage to the original
