You are designing a Windows Azure application that will process images.  The maximum size of an image is 10 MB.   The application includes a web role that allows users to upload images and a worker role with multiple instances that processes the images.   The web role communicates with the worker role by using a Windows Azure Queue.  You need to recommend an approach for storing images that minimizes storage transactions.  What should you recommend？ （）

• A、 Store images in the queue.
• B、 Store images in Windows Azure Blob storage.  Store references to the images in the queue.
• C、 Store images in local storage on the web role instance.  Store references to the images in the queue.
• D、 Store images in Windows Azure Drives attached to the worker role instances. Storereferences to the images in the queue.
