Answer 1

The problem is you do two things on your script. You set the image to deliver the image over the php script.

<?php 
    header('Content-type: image/png');
    echo file_get_contents("http://ip/demo/images/itemimage/Platters.png");
?>

Then you should fetch the image and send the image with echo to the user.

When you want to save the image then you need only fetch the image with file_get_contents and put them to your harddrive what you do at the moment.

I think in your example the echo missing this is why you get the error. You set the content type of the site but you don't deliver any png data.

<?php 
    header('Content-type: image/png');
    $handle = file_get_contents("http://ip/demo/images/itemimage/Platters.png"); 
    file_put_contents(dirname(__FILE__).md5(time()), $handle);
    echo $handle;
?>

Edit: Try something like this. Then he should save the image in the same path.
