won't be tough .. just requiring a simple edit of the
memberlist_resultsbit template
find this:-
Code:
<a href="$userinfo[homepage]" target="_blank"><img src="$stylevar[imgdir_button]/home.gif" alt="home.gif" title="<phrase 1="$userinfo[username]">$vbphrase[visit_xs_homepage]</phrase>" border="0" /></a>
and replace with the code here making some necessary changes.. you may try doing this in your test board first coz it would require a bit of HTML/design editing to match the layout.
