Explanation

Cloud Storage is a cost-effective solution for storing large objects like images, especially for short-term storage. By configuring a lifecycle policy, you can automatically delete objects after 10 days, aligning perfectly with your requirement to remove images after that period. This approach minimizes cost by avoiding the need for active management or scheduled deletion processes. Using Spanner, Firestore, or Bigtable would generally be more expensive and less optimal for storing large files like images, as these services are better suited for structured or semi-structured data rather than binary objects (such as images).
