         'image' => $image
     );  
     echo json_encode($response);

?>

from the code, is there anything I'm doing wrong? Thanks!!! :))

Answer 1

The JSON MIME type is application/json, so you can't send image/jpeg.

I think it would be easier to send the path to the image, and have your JavaScript make the request to the image.

Otherwise, I'm not sure how you are going to recreate that on the client. Date URIs are recommended to be base64 encoded, so if you insist on doing it like this, please call base64_encode() first on it.
