Windows Azure UploadFromStream No Longer Works After Porting to MVC4 - Pointers? - asp.net-mvc-4

Question

Updated my MVC3/.Net 4.5/Azure solution to MVC4.
My code for uploading an image to blob storage appears to fail each time in the upgraded MVC4 solution. However, when I run my MVC3 solution works fine. Code that does the uploading, in a DLL, has not changed.
I’ve uploaded the same image file in the MVC3 and MVC4 solution. I’ve inspected in the stream and it appears to be fine. In both instance I am running the code locally on my machine and my connections point to blob storage in cloud.
Any pointers for debugging? Any known issues that I may not be aware of when upgrading to MVC4?
Here is my upload code:
public string AddImage(string pathName, string fileName, Stream image)
{
var client = _storageAccount.CreateCloudBlobClient();
client.RetryPolicy = RetryPolicies.Retry(3, TimeSpan.FromSeconds(5));
var container = client.GetContainerReference(AzureStorageNames.ImagesBlobContainerName);
image.Seek(0, SeekOrigin.Begin);
var blob = container.GetBlobReference(Path.Combine(pathName, fileName));
blob.Properties.ContentType = "image/jpeg";
blob.UploadFromStream(image);
return blob.Uri.ToString();
}

I managed to fix it. For some reason reading the stream directly from the HttpPostFileBase wasn't working. Simply copy it into a new memorystream solved it.
My code
public string StoreImage(string album, HttpPostedFileBase image)
{
var blobStorage = storageAccount.CreateCloudBlobClient();
var container = blobStorage.GetContainerReference("containerName");
if (container.CreateIfNotExist())
{
// configure container for public access
var permissions = container.GetPermissions();
permissions.PublicAccess = BlobContainerPublicAccessType.Container;
container.SetPermissions(permissions);
}
string uniqueBlobName = string.Format("{0}{1}", Guid.NewGuid().ToString(), Path.GetExtension(image.FileName)).ToLowerInvariant();
CloudBlockBlob blob = container.GetBlockBlobReference(uniqueBlobName);
blob.Properties.ContentType = image.ContentType;
image.InputStream.Position = 0;
using (var imageStream = new MemoryStream())
{
image.InputStream.CopyTo(imageStream);
imageStream.Position = 0;
blob.UploadFromStream(imageStream);
}
return blob.Uri.ToString();
}
