HTML img Tag

HTML img tag: The HTML<img>tag specifies an image in an HTML page. The HTML img tag has two required attributes i.e. src and alt. Images are not technically inserted into an HTML page, images are linked to HTML pages. The <img> tag creates a holding space for the referenced image. In HTML 4.01 align, border, hspace and vspace attributes are supported. But whereas in HTML 5 align, border, hspace, and vspace attributes are not supported.


This HTML <img> tag supports both the global and the event attributes.

Syntax:<img src=”url” alt=”some_text”>

‘src’ attribute

src stands for source. Every image has an src attribute which tells the browser where to find the image you want to display. The URL of the image provided points to the location where the image is stored.

‘alt’ attribute

If the image cannot be displayed then the alt attribute acts as an alternative description for the image. The value of the alt attribute is an user-defined text.

  • Chrome
  • Firefox
