alt attributes are required.. they tell the browser what the graphic is when they cannot see it. the are a requirement of xhtml all DTD's.. if you have a corner image and don't want to say alt="corner image" because IE will give you a tool tip on that one you can use alt="" but the alt is required.
title="" is to provide additional information to the site visitor and will produce a tool tip (in all browsers (alt only does in IE) and even IE will override alt= when there is a title).
