(Use BBCode. You have to have the image on the internet, then you put the URL inside the brackets. For example,<span style="font-weight: bold">[</span>img<span style="font-weight: bold">]</span>http://db.tt/PJNXGl4u[/img] would become<div style="padding: 3px; background-color: #FFFFFF; border: 1px solid #d8d8d8; font-size: 1em;"><div style="text-transform: uppercase; border-bottom: 1px solid #CCCCCC; margin-bottom: 3px; font-size: 0.8em; font-weight: bold; display: block;"><span onclick="if (this.parentNode.parentNode.getElementsByTagName('div')[1].getElementsByTagName('div')[0].style.display != '') {  this.parentNode.parentNode.getElementsByTagName('div')[1].getElementsByTagName('div')[0].style.display = ''; this.innerHTML = '&lt;b&gt;Spoiler: &lt;/b&gt;&lt;a href=\'#\' onClick=\'return false;\'&gt;hide&lt;/a&gt;'; } else { this.parentNode.parentNode.getElementsByTagName('div')[1].getElementsByTagName('div')[0].style.display = 'none'; this.innerHTML = '&lt;b&gt;Spoiler: &lt;/b&gt;&lt;a href=\'#\' onClick=\'return false;\'&gt;show&lt;/a&gt;'; }"><b>Spoiler: </b><a href="#" onclick="return false;">show</a></span></div><div class="quotecontent"><div style="display: none;"><img alt="Image" src="http://db.tt/PJNXGl4u"/></div></div></div>(which is an image I drew of Kate :3))<br/><br/>(Edit: I spoilered it because I forgot how huge it was :S)
