The term "alt tag" is sometimes incorrectly used instead of the correct term "alt attribute".
The alt attribute is used in HTML and XHTML documents to specify alternative text (alt text) that is to be rendered when the element to which it is applied cannot be rendered.
The HTML for this might be something like the following:
<img alt="image name here"
src="http://www.imagefilelocation.com"
width="180" height="135" />
