Definition and Usage

The <img> tag embeds an image in an HTML page.
Notice that 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.
The <img> tag has two required attributes: src and alt.

Browser Support

Internet Explorer Firefox Opera Google Chrome Safari
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.

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" />
Note: When a web page is loaded, it is the browser, at that moment, that actually gets the image from a web server and inserts it into the page. Therefore, make sure that the images actually stay in the same spot in relation to the web page, otherwise your visitors will get a broken link icon. The broken link icon is shown if the browser cannot find the image.
