I have added the following to header.php:-
<h1><a href="<?php bloginfo('siteurl');?>/" title="<?php bloginfo('name');?>"><img src="http://s442965138.websitehome.co.uk/curve1/wp-content/uploads/curvelogo.png/" title="Home" alt="HomeAlt" /></a></h1>
However the image is not displaying on the page. Just a square where it should appear (Chrome. HomeAlt in IE and FF).
Please let me know if you have any idea as to why this is happening...
