In case your boss insists on a regex, and (s)he does not hear to the voice of wisdom, you can try the following regex:

(?si)\s*<img\b(?>(?!src=).)*?\/>\s*

See demo on regex101.

Sample PHP code:

$re = "/(?si)\\s*<img\\b(?>(?!src=).)*?\\/>\\s*/"; 
$str = "<html>\n <img src=\"someurl\" alt=\"something\"  />\n <img  alt=\"something\"  />\n <img  alt=\"somethingelse\"\n       att='val'  />\n<html />"; 
$result = preg_replace($re, "", $str);
