Instead of 'img', you could use HTML’s 'object' element, which allows
for more complex alternative/fallback content:
<object data="infographic.png" type="image/png">
<p>
<!-- alternative text for users that can’t access the image -->
</p>
<!-- and you might include RDFa here, too -->
</object>
As the object’s content is defined to be used as fallback, I think we
can safely assume that search engines know this and that they won’t
penalize content that is marked up according to the HTML specification.
