HTML img tag

Example

An image is marked up as follows:

<img src="angry.gif" alt="Angry face" />

---

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" />
