<img>

img represents an image. This element has no content in itself; it requires the source (src) attribute.

The img is considered an empty element. Most empty elements are self-closing: they do not require a closing tag, e.g., <hr>. HTML and xHTML have different methods:

Element tag:
<img>
Closure:
HTML 4.01 - <img>
HTML 5 - Either closure type
xHTML 1.0 - <img(Single space) />
Example [Alternate Text (alt) Attribute only]:

This is an IMG element lacking the SRC attribute which means you are reading the ALT attribute's text.

Code [HTML 4.01]:
<p><img alt="This is an IMG element lacking the SRC attribute which means you are reading the ALT attribute's text."></p>
Code [xHTML 1.0]:
<p><img alt="This is an IMG element lacking the SRC attribute which means you are reading the ALT attribute's text." /></p>
Example [Basic]:

An Allegorical image representing for when Tinny and Woody Words are used in a single sentence:

1950's photograph of two boys wearing large papier-mâché head pieces.

Code [HTML 4.01]:

<p>An Allegorical image representing for when Tinny and Woody Words are used in a single sentence:</p>
<p><img src="/images/article-illustratives/maskboys_S.png" width="341" height="402"
