Please open CuteSoft_Client\CuteEditor\Scripts\Dialog\Dialog_InsertImage.js and add the following code to the bottom of the page:

 

function reset_hiddens()
{
 //server side alert
 if(hiddenAlert.value)
 {
     alert(hiddenAlert.value);
 }
 if(TargetUrl.value!=""&&TargetUrl.value!=null)
 {
  do_preview()
 }
 //clear the commands..
 hiddenAlert.value="";
 hiddenAction.value="";
 hiddenActionData.value="";
}

 

Hope it helps.
