<A HREF="www.dalleh.com"><img src="images2/bart.gif"></A>
or 
<A HREF="http://www.dalleh.com"><IMG SRC="images2/bart.gif" ALT="Bart" BORDER=0 HEIGHT=148 WIDTH=110> </A>

   Using the width and height of the image, is recommended, if the image did not show the browser would  reserve the space for the image in this case your page keeps the same look, everything stays in the same place where you put it.

   If there is an ugly border around your image link just add BORDER=0 to take it off. An image as a link can take the clicker to another page, a different image, music, or even a file for downloading.
