从服务器获取图像

Question

I uploaded image to the server using php.And i also generate a random image number after the id.Now the name of the uploaded image like 6_1.jpg, 5_4.jpg etc, Where 1st number is the id (before _) and other is randomly generated number(after _). My codes are as below

function upload_receipt_img(){
    $random_digit = rand(0,9);          
    $receipt_id = $_POST['id'];      
        if (isset($_POST['data_url'])) {      
            $file = $receipt_id._.$random_digit.'.jpg';
            $img = substr($_POST['data_url'], strpos($_POST['data_url'], ",") + 1);
            $decodedData = base64_decode($img);
            $success = file_put_contents('assets/receipt_img/' . $file, $decodedData);
            //resize main image
            $source_path = "assets/receipt_img/" . $file;
            $destination = "assets/receipt_img/" . $file;
            $newwidth = 350;
            $this->resizeImg($newwidth, $source_path, $destination);
            $data['img'] = 'assets/receipt_img/' . $receipt_id.$random_digit.'.jpg';
        }
    $this->closeConnection();
    echo $receipt_id;

}

Now how can i show images from the server to my home page.Please help me.Thanks in advance

Use header function as

<?php 
  header('Content-type: image/jpeg'); 
  readfile($destination); // image file path
?>

for each image.
