Captcha image src issue

Hi I am trying to use CI's captcha . All though my captcha is getting created , the src of the captcha img that CI is generating is not correct .

I have an User controller with register function like below : (Complete Controller is at [font=Helvetica, Arial, sans-serif]pastebin https://pastebin.com/pSskpuy0)[/font]

PHP Code:
public function register(){ 
$this->form_validation->set_rules('user_name' 'Username' 'trim|required|max_length[32]'); 
$this->form_validation->set_rules('captcha' 'Captcha' 'trim|required|max_length[32]|callback_check_captcha');
$this->form_validation->set_rules('confirm_password''Confirm Password','trim|required|min_length[5]|max_length[12]|matches[password]');
if (
//Captcha code 
//Captcha Config 
$vals = array(
'img_path' => './captcha/',
'img_url' => './captcha/',
'img_width' => '150',
'img_height' => 30,
'expiration' => 7200,
'word_length' => 8,
'font_size' => 16,
'img_id' => 'Imageid',
'font_path' => '/fonts/Open.ttf',

// White background and border, black text and red grid
'colors' => array(
'background' => array(255255255),
'border' => array(255255255),
'text' => array(000),
'grid' => array(2554040)
//Create the Captcha
$cap create_captcha($vals);

// Store The Created Captcha in DB for Verification 
$data = array(
'captcha_time' => $cap['time'],
'ip_address' => $this->input->ip_address(),
'word' => $cap['word']
//Load View
$this->load->view('register' $data);
}else {
$this->session->set_flashdata('user_registered','You are Successfully Registered and can Log in ');

[font=Helvetica, Arial, sans-serif][font=Helvetica, Arial, sans-serif]If you see the above code I am setting the 'img_path' to './captcha/'(using the root relative method) . I have this folder captcha in the root .[/font][/font]

[font=Helvetica, Arial, sans-serif][font=Helvetica, Arial, sans-serif]I my view I have :[/font][/font]

PHP Code:
<div class="form-group">
   <label>Enter UserID</label>
   <input type="text" class="form-control" name="user_name"  placeholder="Enter Your UserId">
 <div class="form-group">
   <label>Enter Your Email</label>
   <input type="email" class="form-control" name="email"  placeholder="Enter Your Email">
 <div class="form-group">
   <label>Enter Your Password </label>
   <input type="password" class="form-control" name="password"  placeholder="Enter Password">
 <div class="form-group">
       <label>Re-enter Password </label>
       <input type="password" class="form-control" name="confirm_password"  placeholder="Renter Password">
 <?php echo $image ?>
  <div class="form-group">
        <label>Solve Captcha </label>
        <input type="text" class="form-control" name="captcha" >
   <button type="submit" class="btn btn-primary">Submit</button>
  <?php echo form_close();?>

[font=Helvetica, Arial, sans-serif][font=Helvetica, Arial, sans-serif][font=Arial,]The problem is my image is not showing up . When inspected the captcha image I found it to be correct like below :[/font][/font][/font]

<img id="Imageid" src="./captcha/1551023447.5228.jpg" style="width: 150; height: 30; border: 0;" alt=" ">

[font=Helvetica, Arial, sans-serif][font=Helvetica, Arial, sans-serif][font=Arial,][font=Arial,]However , the src is actually getting 'computed' to : /login/user/captcha/1551023447.5228.jpg]http://[::1]/login/user/captcha/1551023447.5228.jpg  instead of [font=Arial,] /login/captcha/1551023447.5228.jpg]http://[::1]/login/user/captcha/1551023447.5228.jpg . [/font][/font][/font][/font][/font]

[font=Helvetica, Arial, sans-serif][font=Helvetica, Arial, sans-serif][font=Arial,][font=Arial,][font=Arial,][Image: FV0ce.png][/font][/font][/font][/font][/font]

[font=Helvetica, Arial, sans-serif][font=Helvetica, Arial, sans-serif][font=Arial,][font=Arial,][font=Arial,][font=Arial,]Could somebody tell me why the src is pointing to /login/user/captcha/1551023447.5228.jpg]http://[::1]/login/user/captcha/1551023447.5228.jpg all though it should be /login/captcha/1551023447.5228.jpg]http://[::1]/login/captcha/1551023447.5228.jpg and how we can fix this ? Surprisingly the same code is running all right in another project with same directory structure .[/font][/font][/font][/font][/font][/font]

You told it where to point. Your URI is "/login/user/register, so the browser thinks you are in the "/login/user" folder, and the reference "/login/user/captcha..." is correct from its perspective.

If you actually meant to refer to something in your document root, then the reference should be "/captcha/...", without the leading "." Undecided
