html - Image title attribute or link title attribute or both?

Question

Let's say I have a list of images on the page, that are wrapped within links. So when u click an image it gets you to a page that displays the larger image

How should I handle title tags here?

Do I put the image title on both the image and the link, or just the image? Does it matter if the title is the same as the "alt" attribute?

<a title="image description" href="#"><img title="image description" alt="image description" src="image.jpg"></a>

Answer 1

The image title attribute should describe the image.

The link title attribute should describe the target of the link.

<a title="view larger version" href="#">
  <img title="image description" alt="image description" src="image.jpg">
</a>
