I've been wondering about this for a long time. Is there any difference between alt="image description" and title="image description" image tags, as far as any help with SERP's are concerned? FF still doesn't support the alt image tag, but it does pop-up the text when the title="" tag is used when hovering an image. So I'm wondering if the title="" can be used in lieu of the alt image tag? Do the SE's still treat a title="" tag the same as the alt tag? Or does this make absolutely no difference either way?

Thanks.
