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.
