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">
     <!-- alternative text for users that can’t access the image -->
    <!-- and you might include RDFa here, too -->

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.
