# 📸 Random Photo Viewer
2+
3+
A simple and fun JavaScript project that displays a random image every time you click a button.
4+
5+
## 🔍 Concepts Demonstrated
6+
- Arrays and random selection in JavaScript
7+
- DOM manipulation and event handling
8+
- CSS transitions for smooth effects
9+
10+
## 🚀 How It Works
11+
1. Images are stored in an array.
12+
2. Each time the button is clicked, a random index is chosen.
13+
3. The image source is updated, and a fade transition is applied.
14+
15+
## 🧩 Bonus Idea
16+
You can replace the local array with an API like Unsplash to load new random images dynamically.
