When answering this question, start by explaining the basic structure of an image uploader, focusing on the user interface, the server-side logic, and the database where the images will be stored. Discuss the technical considerations such as image size limits, file formats supported, and how to handle errors or failed uploads gracefully. It is also crucial to mention security considerations, like how to ensure that uploaded files are images and do not contain malicious code, and how to securely store and serve uploaded images. Address the need for scalability and efficient retrieval and storage methods, considering potential high volumes of image uploads. Don’t forget to consider user experience, outlining how you would make the uploader user-friendly, and potentially touch on how you would make the uploader accessible. Finally, be clear on how different components in your design communicate and how the solution scales with increasing load, while maintaining reliability and performance.
