    Find out how many img tags there are in the string.

    If there is more than one, change the first one to something else, strip the rest of the image-tags and put back in the first one.

    I cant write any code right now, I have a baby watching Totoro in my arm, but the above should be pretty easy.

    You can use preg_replace()
    Please write what you exactly want "echo limitImage($string);" to show with your example if you want more help.

    function limitImage($string)
    {
    	$string = preg_split('/(<img[^>]+>)/i', $string, 2, PREG_SPLIT_DELIM_CAPTURE);
    	return $string[0] . $string[1] . strip_tags($string[2]);
    }
