Conditional tags

Hi

Im new to conditional tags and cannot seem to find what Im looking for thro the docs and forum.

Im using the conditional tags in my header.php to display a different image background for individual pages, i.e

} elseif (is_page('support')) {
             echo "<div id=\"headimagespace\" class=\"imagesupport\">Support</div>";

etc

My homepage is a static page ‘home’ and my blog is under ‘news’

What conditional tag would I use so the I can control what image appears when a visitor clicks ‘news’ to see my blog?

Thanks for any help offered
