HTML <img> tag
Example
An image is marked up as follows:
| <img src="angry.gif" alt="Angry face" /> |
 (more examples at the bottom of this page) |
Definition and Usage
The <img> tag embeds an image in an HTML page.
The <img> tag has two required attributes: src and alt.
Browser Support
The <img> tag is supported in all major browsers.
Differences Between HTML and XHTML
In HTML the <img> tag has no end tag.
In XHTML the <img> tag must be properly closed.
The "align", "border", "hspace", and "vspace" attributes of the image element
were deprecated in HTML 4.01, and are not supported in XHTML 1.0 Strict DTD.
Tips and Notes
Tip: The alt attribute is meant to be used as an alternative text if the image is not available, not as a mouse-over text. To
show a mouse-over text on images or image-maps, use the title attribute, like this: <img src="angry.gif" alt="Angry face" title="Angry face" />
Required Attributes
DTD indicates in which DTD the attribute is allowed. S=Strict, T=Transitional, and F=Frameset.
