Hi, this is the code

Link to us:<br>
<form><textarea cols="110" rows="3" onClick='highlight(this);'><a href="<? echo $url; ?>">
<img src="<? echo $url; ?>/button.gif"></a></textarea></form>
<br>
<a href="<? echo $url; ?>">
<img src="<? echo $url; ?>/button.gif"></a>

</div><br><br>

This is the code at this Tools Page
I am having problem for linkback. the code doesn't seem to work. Plus the url generated in example is http://free-images-upload.com/www.free-images-upload.com

Please help me see what is wrong. thanks very much
