UL links wont work in index.php

I’m creating my own wordpress theme from scratch (my first time doing so). Everything looks great so far, but for some reason some of the image links in one of my unordered lists aren’t registering as links. There are 6 images, and only one of theme (the last one) is actually working as a link. I’ve pasted the code below. Can anyone tell me what I’m doing wrong, or what I should do?? (if you want to see it live, the site is http://www.VeganSutra.com). btw, I havent done anything with the bottom four links yet, which is why they are blank.

<div class=”top_nav”>

• <img border=”0″ src=”<?php echo bloginfo(‘template_directory’) . ‘/images/nav/connect.png’; ?>” />
• <img alt=”Email Us” border=”0″ src=”<?php echo bloginfo(‘template_directory’) . ‘/images/nav/mail.png’; ?>” />
• “><img alt=”RSS Feed” border=”0″ src=”<?php echo bloginfo(‘template_directory’) . ‘/images/nav/rss.png’; ?>” />
• ” />
• <im… alt=”Follow Us” border=”0″ src=”<?php echo bloginfo(‘template_directory’) . ‘/images/nav/twitter.png’; ?>” />
• ” />
• <img alt=”Tumble With Us” border=”0″ src=”<?php echo bloginfo(‘template_directory’) . ‘/images/nav/tumblr.png’; ?>” />
• <img alt=”About Us” border=”0″ src=”<?php echo bloginfo(‘template_directory’) . ‘/images/nav/about.png’; ?>” />
• <img alt=”Contact Us” border=”0″ src=”<?php echo bloginfo(‘template_directory’) . ‘/images/nav/contact.png’; ?>” />
• <img alt=”Our Blogs” border=”0″ src=”<?php echo bloginfo(‘template_directory’) . ‘/images/nav/blog.png’; ?>” />
• <img alt=”Links to other lovely sites” border=”0″ src=”<?php echo bloginfo(‘template_directory’) . ‘/images/nav/links.png’; ?>” />

</div>
