## CSS Images
This helps in adding an image to a website. CSS can handle images like JPG, PNG or other raster format. There are two types images: plain images which are sometimes referenced with a url, and dynamically generated images which are generated by some element.

#### Code Sample

```<img src="picture.jpg" alt="Picture" width="100" height="100">```

* **src:** It consists the value of the path to the required image.
* **alt:** This is a text description of the image and is useful if the image cannot be viewed by a visitor. It also allows the image on your page to rank in image search results for search engines such as Google.
* **width:** This specifies a width for the image(can be percent or px or auto).
* **height:** This specifies a height for the image(can be percent or px or auto).

#### CSS Defaults

The `img` element will be rendered by default in most browsers to be displayed as an inline-block display type unless specified otherwise.

```
img {
  display: inline-block;
}
```

#### More Information:
<!-- Please add any articles you think might be helpful to read before writing the article -->
It is advised to change any one parameter, either height or width, to get a proportionate image. Changing both dimensions results in forced scaling and is not advisable.

##### Datatypes
<a title="The <image> CSS data type represents a 2D image. There are two kinds of images: plain images, typically referenced using a URL, and dynamically-generated images, like those generated with <gradient> or element(). Images can be used with numerous CSS properties, such as background-image, border-image, content, list-style-image, and cursor." href="/en-US/docs/Web/CSS/image"><code>&lt;image&gt;</code></a>

##### Image Sprites
An image sprite is a collection of images put into a single image.
A web page with many images can take a long time to load and generates multiple server requests.
Using image sprites will reduce the number of server requests and save bandwidth.

```
#home {
    width: 46px;
    height: 44px;
    background: url(img_navsprites.gif) 0 0;
}
```
