A new tab was added to the admin toolbar providing a drag-and-drop upload area with a hotel selection dropdown populated from the vendor database. On the backend, a dedicated handler processes uploads with validation for file type, size, and hotel selection, then stores images on the server filesystem while recording references in the MySQL database. Authentication is enforced through session-based access controls, and all records include audit tracking for accountability. Error handling covers the full workflow — from client-side input checks through server-side file operations and database transactions, with automatic cleanup if any step fails.
