HTML Element: <img>
[this page | pdf | back links]
The
HTML <img> element indicates an
image. It technically has two required attributes, namely src (the source of the image) and alt (the alternative text displayed if
the image cannot be found or cannot be displayed by the browser), although the alt attribute can typically be
dispensed with. Images are not technically inserted into an HTML page but
instead are linked to the page. The <img>
element therefore creates a placeholder that will include the image once the
page is rendered (and the image retrieved by the rendering process from its source
location).
The attributes it can take
(other than HTML
global attributes and HTML event attributes)
