You leave the alt attribute blank if the image is for decoration. For
example:

<h1><img src="companylogo.png" alt="" height="100" width="200">Company
Name</h1>

or

<h1><a href="index.php" title="Return to Company Index Page"><img
src="companylogo.png" alt="" height="100" width="200">Company Name</a>
</h1>

vs

<p><img src="rolo.png" alt="Our cat Rolo sitting at the window"
height="100" width="100"> This picture of our Maine Coon, Rolo, was taken
when we first got her. Rolo loves to sit at the window and wait for the
birds, then she "sings" to them.</p>

Notice 1 and 2 have no alt text because they are for decoration. The
second example uses the title attribute to give the user a hint to the
destination. The third example DOES use have alt text because it is NOT
purely for decoration.
