    $domDocument = new DOMDocument();

    $domDo

You just need to add 2 flags to the loadHTML() method: LIBXML_HTML_NOIMPLIED|LIBXML_HTML_NODEFDTD. I.e.

$domDocument->loadHTML($text, LIBXML_HTML_NOIMPLIED|LIBXML_HTML_NODEFDTD);

See IDEONE demo:

$text = '
Hi, this is a test, here is an image Because I like Beer!
';
$domDocument = new DOMDocument;
$domDocument->loadHTML($text, LIBXML_HTML_NOIMPLIED|LIBXML_HTML_NODEFDTD);
$imageNodeList = $domDocument->getElementsByTagName('img');

foreach ($imageNodeList as $Image) {
      $Image->setAttribute('src', 'lalala');
      $domDocument->saveHTML($Image);
}

$text = $domDocument->saveHTML();
echo $text;

Output:

Hi, this is a test, here is an image Because I like Beer!
