Azure存储图像上载无法正常工作

Question

I have an issue with Azure Storage and I am not 100% sure how to fix it. I need to be able to take an image and upload it to a container. This is my first time using Azure Storage. Here is some of the code:

require_once 'vendor\autoload.php';
require_once 'WindowsAzure\WindowsAzure.php';
use WindowsAzure\Common\ServicesBuilder;
$connectionString = 'DefaultEndpointsProtocol=http;AccountName=buyeraudit;AccountKey=MYKEY';
$blobRestProxy = ServicesBuilder::getInstance()->createBlobService($connectionString);

here is another part:

$newFileName = $pro[0]['proid'] .'.'. $picExt;
rename($_FILES['pic']['tmp_name'], $newFileName);
$blobRestProxy->createBlockBlob("images", $newFileName,  file_get_contents($_FILES['pic']['name']));

I just set the sdk up so it may also be an issue that has to do with that. I appreciate all help and thank you for helping.
