You could parse the HTML using `DOMDocument` class and perform all the changes you want :

$content = '<p><img alt="" src="uploaded_files/12/images/_gzyefj8rwhokhhzgprzltl72ejkfbmt4t8yenimkbvvk0ktmf0xjctabnaljim9.jpg" style="height:285px; width:285px" /></p>';
$html = new DOMDocument();
$html->loadXML($content);
$img = $html->getElementsByTagName('img')[0];
$img->setAttribute('src', 'http://example.com/' . $img->getAttribute('src'));
$content = $html->saveHTML();

echo $content;

   $html = new DOMDocument();
            $html->loadXML($_POST['quick_email']);
            $img = $html->getElementsByTagName('img')[0];
            $img->setAttribute('src', $_SERVER['HTTP_HOST'] . $img->getAttribute('src'));
            $content = $html->saveHTML();
