[TYPO3] function openPic nightmare

[Bartosz Aninowski]

Hi
Can you tell me how to remove following js code from document header?
<script type="text/javascript">
 /*<![CDATA[*/
<!--
 function openPic(url,winName,winParams) { //
  var theWindow = window.open(url,winName,winParams);
  if (theWindow) {theWindow.focus();}
 }

// -->
 /*]]>*/
</script>
I've tried this
config.setJS_openPic=0
config.removeDefaultJS = external
config.inlineStyle2TempFile = 1
but nothing works

p.s versio typo3-4rc1
