    I have a little coding I need help with and hope somebody can lend assistance.

    Here is what I am trying to do, currently this works very well but I need to not replace any image tag that has an alt tag in it. Thanks.

    preg_replace( "#<img(?:.+?)src=[\"'](\S+?)['\"][^>]+?>#is", "image holder", $comment );

    Maybe something like this?

    

function replaceNotAlt ($alt){
  
  if (preg_match('#alt\s*=\s*([\'"])[^>]+\1#', $alt[0], $matches) )
  { 
    return $alt[0];
  }
  else
  { 
    // return what you want here
  }

}

$text = preg_replace_callback('#<img[^>]+?>#is', "replaceNotAlt", $text );
