Don’t use regular expressions to parse HTML. Instead, use something like the DOMDocument that exists for this very reason:

$html = 'Sample text. Image: <img src="foo.jpg" />. <img src="bar.png" />';
$doc = new DOMDocument();
$doc->loadHTML( $html );

$images = $doc->getElementsByTagName("img");

for ( $i = 0; $i < $images->length; $i++ ) {
  // Outputs: foo.jpg bar.png
  echo $images->item( $i )->attributes->getNamedItem( 'src' )->nodeValue;
}

You could also get the image HTML itself if you like:

// <img src="foo.jpg" />
echo $doc->saveHTML ( $images->item(0) );
