     The work-around is to check the file extension at the point where 
the user attempts to submit the form and cancelling such submission if 
this validation is unsuccessful.  However, note that the user may 
disable JavaScript execution to circumvent your validation attempts.  
Thus, the only sure-fire validation is performed by server-side code 
such as ASP, JSP, PHP, etc.  The following is the JavaScript-based 
validation:
var valid_extensions = /(.jpg|.jpeg|.gif)$/i;
function valid_extension(fld)
{
  if (valid_extensions.test(fld.value)) return true;
  alert('The selected file is of the wrong type.');
  fld.select();
  fld.focus();
  return false;
}
    Use the above JavaScript definitions with the following sample 
HTML:
<form onsubmit="return valid_extension(this.elements['file_upload'])">
  <fieldset>
    <input type="file" name="file_upload" size="40">
  </fieldset>
</form>
