**Example 5: Generating dropdownlist with option groups.**

If you need to generate dropdownlist using both `optgroup` and `option` tags use the following code.

## CHtml::image() method
 
 
 
```php 
public static string image(string $src, string $alt='', array $htmlOptions=array ( ))
 
```
 
 
 
Generates a image tag.
 
 
***
 
 
**Example 1: Image only**
 
 
```php 
<?php echo CHtml::image(Yii::app()->request->baseUrl.'/img/image.png'); ?>
 
```
 
 
**HTML Output:**
 
 
 
```php 
<img src="/img/image.png" />
 
```
 
 
 
***
 
 
**Example 2: Image with alt attribute**
 
 
```php 
<?php echo CHtml::image(Yii::app()->request->baseUrl.'/img/image.png', 
 
'this is alt tag of image'); ?>
 
```
 
 
**HTML Output:**
 
 
 
```php 
<img src="/img/image.png" alt="this is alt tag of image" />
 
```
 
 
 
 
***
 
 
**Example 3: Add width, height and others attribute for image**
 
 
```php 
<?php echo CHtml::image(Yii::app()->request->baseUrl.'/img/image.png',
 
      'this is alt tag of image',
 
      array('width'=>'100px','height'=>'100px','title'=>'image title here')); ?>
 
```
 
 
**HTML Output:**
 
 
 
```php 
<img src="/img/image.png" alt="this is alt tag of image" title="image title here" width="100" height="100" />
 
```

<?php $image = CHtml::image(Yii::app()->request->baseUrl.'/img/image.png',
 
      'this is alt tag of image');
 
      
 
      echo CHtml::link($image,array('book/view','id'=>'book_id')); ?>
 
```
 
 
**HTML Output:**
 
 
 
```php 
<a href="index.php?r=book/view&id=book_id"><img src="/img/image.png" alt="this is alt tag of image" /></a>
 
```
