The code is fine as it is. The text inside the <a> element is specifying the link destination, so the image just needs a null 'alt' attribute, which it has.

If there was no text, the image would need a descriptive 'alt' attribute.

Subject: Re: Anchor images - pixel sized & alt text

Here is a snippet of one of them, it does appear to be a link:

<span class="d_nb_ni">
<a href="/d2l/lp/ouHome/defaultHome.d2l">
<img src="/d2l/img/lp/pixel.gif" class="d_nb_s" alt="" />
<span>My Home</span>
</a>
</span>

But like I said the image is 1px, should alt be filled or should the programmers figure out a diff way for styling content?

Thanks

Hi,

Could you please provide the HTML code of the enclosing link?
Is this a named anchor :
    <a name="name_attribute_deprecated_but_still_used"
id="name_attribute_deprecated_but_still_used"><img src="path/image.png"
alt=""></a>
or a link to some page :
    <a href="something.php"><img src="path/image.png" alt=""></a>

For example, the Accessiweb checklist, which is based on WCAG 2.0,
excludes "a" elements without an "href" attribute from the links that
should have text (or alternative text) as content :
http://www.braillenet.org/accessibilite/referentiel-aw21-en/index.php#crit-6-6
(you can follow links to the glossary for more details).
