캡챠(Captcap)관련 문의입니다. 채택완료

답변주셔서 감사합니다 그럼 캡챠의 이미지주소 자바스크립트를 확인하면 되는건가요? javascript:void(0) 이부분인가요?
kcaptcha.js 이부분을 열어봤는데 여기 같은데~ 뭐가 잘못 된걸까요~?


$(function(){
var mp3_url = "";

$(document).on( "click", "#captcha_reload", function(){
$.ajax({
type: 'POST',
url: g5_captcha_url+'/kcaptcha_session.php',
cache: false,
async: false,
success: function(text) {
$('#captcha_img').attr('src', g5_captcha_url+'/kcaptcha_image.php?t=' + (new Date).getTime());
}
});

$.ajax({
type: 'POST',
url: g5_captcha_url+'/kcaptcha_mp3.php',
cache: false,
async: false,
success: function(url) {
if (url) {
mp3_url = url + "?t="+new Date().getTime();
$("#captcha_audio").attr("src", mp3_url);
}
}
});
});

방금 확인해 봤는데~
kcaptcha.lib.php 에서
$html .= "\n".'<img src="javascript:void(0);" alt="" id="captcha_img">';
이 부분인 것 같은데요..

여기를 어떻게 수정해야하나요?
