Images
Images are a staple of any web designer, so it is very important 
that you understand how to use them properly. 

Use the <img /> tag to place an image on your web page.

The <img> tag is empty, which means that it contains attributes only, 
and has no closing tag. 

To display an image on a page, you need to use the src attribute. 
Src stands for "source".

The value of the src attribute is the URL of the image you want to display. 
Example:

<img src="1.jpg" />

Output:


The required alt attribute specifies an alternate text for an image, 
if the image cannot be displayed.

The value of the alt attribute is an author-defined text:

<img src="boat.jpg" alt="safcode" />

You can also use width and height attribute in img tag:

<img src="1.jpg" width="600" height="380"/>
