Q. What error handling should I incorporate and how do I serve the uploaded images?

 Answer:

• Wrap upload middleware in try/catch or pass errors to Express’s error handler (e.g. handle MulterError)

• Return meaningful error responses for file size exceed, invalid type, or missing files

• On success, respond with the URL or path to the stored image(s)

• To serve images, use Express static middleware (e.g. app.use(‘/uploads’, express.static(‘uploads’))) so clients can fetch by URL (e.g. /uploads/filename.jpg)

• Optionally, delete unused/old files, validate file existence before serving, and add caching headers
