amazon web services - AWS S3 display file inline instead of force download

Question

For some reason files in my S3 bucket are being forced as downloads instead of displaying in-line so if I copy an image link and paste it into address bar and then navigate to it, it will promote my browser to download it. Instead I actually have to click on open image to go to the url.

Any ways to change the way files are served from S3

$client->putObject(array(
        'Bucket'     => 'buckname',
        'Key'        => $destination,
        'SourceFile' => $source,
        'ContentType' =>'image/jpeg', //<-- this is what you need!
        'ACL'          => 'public-read'//<-- this makes it public so people can see it
    ));
