Applies to content using image-based submit buttons.
This technique relates to:
For input elements of type 'image', the alt
attribute of the
input
element is used to provide a functional label. This
label indicates the button's function, but does not attempt to describe the image.
The label is especially important if there are multiple submit buttons on
the page that each lead to different results.
The input
element is used to create many kinds of form
controls. Although the HTML DTD permits the alt
attribute on
all of these, it should be used only on image submit buttons. User agent
support for this attribute on other types of form controls is not well
defined, and other mechanisms are used to label these controls.
An input
element with an alt
attribute
<form action="http://example.com/prog/text"> http://example.com/prog/text-read" method="post"> <input type="image" name="submit" src="button.gif" alt="Submit" /> </form>

For all input elements that have a type attribute value of "image", check for the presence of an alt attribute.
