I have the following code that allows me to successfully upload files to my S3 bucket.

$keyName = 'test_example/' . basename($_FILES["fileToUpload"]['tmp_name']); $pathInS3 = 'https://s3.eu-west-2.amazonaws.com/' . $bucketName . '/' . $keyName; //Add it to S3 try { $s3->putObject( array( 'Bucket'=>$bucketName, 'Key' => $keyName, 'contentType' => 'image/png', 'SourceFile' => $keyName, 'StorageClass' => 'REDUCED_REDUNDANCY' ) ); } catch (S3Exception $e) { die('Error:' . $e->getMessage()); } catch (Exception $e) { die('Error:' . $e->getMessage()); }

The problem is that they download instead of displaying the image. I've looked around and tried adding: 'contentType' => 'image/png' and this doesn't change anything. The file is still uploaded as a Value application/octet-stream rather than a Jpg image. Is there a way to change this?
