well it should be replaced by :
Code:
<a href="external.php?forumids=$forum[forumid]"><img src="$stylevar[imgdir_misc]/rss_small.gif" border="0" width="13" height="11" hspace="2" alt="Subscribe to this feed $forum[title]"></img></a>
so that there will be no more w3c html markup validation errors!! Bingo!
that will make it 100% w3c validated!
thanks for mod though!
