How do I show an image from my Amazon S3 on my website?

Question

I have my pictures on Amazon S3. The pictures are private and not public so I can not show them with a direct link s3.amazonaws/bucket_name/key_name/image_name.jpg

I know the image names on Amazon S3. How do I show for example the Amazon S3 images flower.png and house.png on my website with PHP?

For those who needs this behavior with AWS SDK v3, if you directly call getObjectUrl with '+10 minutes' as third parameter, it will always return the plain URL. That's because the method changed. To get the pre-signed link, do the following:

//Get an instance of S3 Client. This is one one to do it:
$s3Client = new S3Client([
    'version'     => 'latest',
    'region'      => 'us-west-2', //Region of the bucket
    'credentials' => array(
        'key' => 'YOUR-ACCOUNT-KEY',
        'secret'  => 'YOUR-ACCOUNT-SECRET',
    )
]);

//Get a command to GetObject
$cmd = $s3Client->getCommand('GetObject', [
    'Bucket' => 'YOUR-BUCKET-NAME',
    'Key'    => 'YOUR-FILE-KEY'
]);

//The period of availability
$request = $s3Client->createPresignedRequest($cmd, '+10 minutes');

//Get the pre-signed URL
$signedUrl = (string) $request->getUri();
