## 🔧 Technical Details

### HTML Structure:
```html
<div class="col-product">
    <img src="product-image.jpg" 
         alt="Product Name" 
         class="cart-product-image"
         onerror="this.src='/img/default.png'">
    <div class="product-info">
        <span class="product-name-text">Product Name</span>
        <button class="btn-add-note">Note</button>
    </div>
</div>
```

### CSS Styling:
```css
.cart-product-image {
    width: 45px;
    height: 45px;
    object-fit: cover;
    border-radius: 6px;
    border: 2px solid #e0e0e0;
    background: #f8f9fa;
}
```

### JavaScript Cart Object:
```javascript
{
    product_id: 1,
    variation_id: 1,
    name: "Samsung Galaxy S21",
    price: 500,
    sku: "SAM-S21",

## 🎯 Default Image Location

```
public/img/default.png
```

- Format: PNG
- Content: Simple placeholder icon

## 🖼️ Image Fallback Chain

```
1. Product's actual image
   ↓ (if not available)
2. Default.png from public/img/
   ↓ (if not available)
3. Browser's broken image icon
```

## 📊 Image Display Rules

### Product Card:
- Shows product image
- Falls back to default.png
- `onerror` handler for safety

### Cart Item:
- Shows product image from cart data
- Falls back to default.png
- `onerror` handler for safety

### Search Results:
- Image included in search data
- Passed to cart when selected
- Same fallback mechanism

## 🎨 Responsive Behavior

### Desktop:
- Image: 45x45 pixels
- Clear and visible
- Proper spacing

### Tablet:
- Image: 45x45 pixels
- Maintains aspect ratio
- Responsive layout

### Mobile:
- Image: 40x40 pixels (slightly smaller)
- Still visible
- Optimized for small screens

## 🐛 Troubleshooting

### Image نہیں دکھ رہی؟

**Check 1: Product میں image ہے؟**
```sql
SELECT id, name, image FROM products WHERE id = YOUR_PRODUCT_ID;
```

**Check 2: Image file موجود ہے؟**
```bash
# Check if file exists
ls public/uploads/products/your-image.jpg
```

**Check 3: Default image موجود ہے؟**
```bash
# Check default image
ls public/img/default.png
```

### Broken Image Icon دکھ رہا ہے؟

**Solution 1: Create default.png**
```bash
# Create a simple placeholder image
# Size: 200x200 pixels
# Save as: public/img/default.png
```

**Solution 2: Check image permissions**
```bash
# Make sure images are readable
chmod 644 public/uploads/products/*.jpg
chmod 644 public/img/default.png
```

### Image بہت بڑی/چھوٹی ہے؟

**Adjust CSS:**
```css
.cart-product-image {
    width: 50px;  /* Increase size */
    height: 50px;
}
```
