title: Should the TITLE attribute be on images or parent links for SEO?
body: <p>When it comes to linked images and SEO, should the <code>title</code> attribute be used on the <code>&lt;img&gt;</code> tag, the parent <code>&lt;a&gt;</code> tag or both?</p>
  
  <p>Common practice seems to be to add the <code>title</code> attribute to the <code>&lt;a&gt;</code> tag. But is this best for SEO? Would there be any harm in adding it to both tags? If not, is there harm in the <code>title</code> text being identical on both?</p>
  
  <p>P.S. I am aware that you should almost always use the <code>alt</code> attribute on <code>&lt;img&gt;</code> tags regardless of the <code>title</code> attribute.</p>
