Ajax and returning image created by PHP GD

Question

I have a PHP script that generates an image with PHP GD. After it generates the image, it saves it, and send this output when called by Ajax:

imagejpeg($img_data         


        

Answer 1

You should modify the header before doing the echo $img_data;

header("Content-Type: image/jpeg");
header("Content-Length: " .sizeof($img_data));
