    id INT AUTO_INCREMENT PRIMARY KEY,
    title VARCHAR(255) NOT NULL,
    description TEXT,
    image_url VARCHAR(500),

**Images not loading?**
- Verify image URLs are correct
- Use full URLs (http://...) or relative paths (assets/img/...)
- Check file permissions on upload directory

**Styles not applying?**
- Clear browser cache (Ctrl+Shift+Del)
- Check `/css/site.css` is loaded
- Verify no conflicting CSS rules

**JavaScript not working?**
- Check browser console for errors (F12)
- Verify JavaScript is enabled
- Check `/js/main.js` is included
