image protection in codeigniter

Question

I am using the following code in my controller:

//function to protect images from being accessed directly.
function getImage($img_id){


      //code to auth         


        

Answer 1

Your problem is that you are outputing text to the browser, and then the image. The browser will try to render the image but it will be corrupted.

header("Content-type: image/jpeg");
if(file_exists($filepath)){
    echo "we are here";
    $img_handle = imagecreatefromjpeg($filepath) or die("");
    echo $img_handle;
    ImageJpeg($img_handle);
}

Also, if you want to do an echo you can't send an header saying "hey, this is a jpeg image".
