Interactive Image Gallery & Drag-and-Drop System
Image Gallery is a modern React-based interactive image gallery application that allows users to view, reorder, select, and upload images directly in the browser without any backend. Built with Create React App and powered by dnd-kit, it provides a smooth drag-and-drop experience, bulk image selection, and client-side image uploads using object URLs. The project is deployed on Netlify and optimized for fast, lightweight performance.

Image Gallery is a fully client-side image management and interaction system built with React. It enables users to visually organize images through drag-and-drop reordering, select multiple images for bulk actions, and upload new images directly from their device. The application uses in-memory state management and requires no backend, making it fast, portable, and easy to deploy.
