如何更改此PHP代码以显示图像而不是文本？ [关闭]

I have this line of code, it works fine. But instead of showing the text 'Login via Facebook' I want to show the the facebook connect button (image). How do I do that?

<li><a href="#" onclick="aw_fb_login(); return false;"><?php echo $this->helper('fbintegrator')->__('Login via Facebook'); ?></a><li>

Thanks

I'd start with this and go from there:

helper('fbintegrator')->__('<img src="/path/to/facebookConnect.png" />');

<li><a href="#" onclick="aw_fb_login(); return false;">
 <?php echo helper('fbintegrator')->__('<img src="/path/to/image.png" alt=""/>'); ?>
</a><li>
