Do following using addslashes() function, so it will help easily to insert update html to

UPDATE `Pages` SET `content`= addslashes('<div id="intro">
<div id="about" align="left">
<h2 class="bigHeader" dir="rtl"HEADER</h2>
<img src="img/Med-logo.png" alt="" />
<div id="wellcomePage" class="text-left text" dir="rtl">
<p>...some words....</p>
<p>.some words....</p>
<p>&nbsp;</p>
</div>
</div>
</div>')
