[themes] Read more link in node teaser

Hi there Drupal droogs,

I've been using the following code in the node tpl file to create a read more link in the node teaser:

<?php print "<a href='/" . $node->links["node_read_more"]["href"] . "' class='readmore' title='" . $node->links["node_read_more"]["attributes"]["title"] . "..' >" . '<img src="' . base_path() . path_to_theme() . '/images/read-more.gif" width="120" height="40" alt="" />' . "</a>"; ?>

Now $node->links["node_read_more"]["href"] works fine at creating the right URL until I put the site into a sub directory, and then instead of the links being /themes/?q=node/62 they are /node/62... which is wrong

Does anybody have any ideas what I can do to sort this problem out?

Regards,

Andy
