most all the photos in the home page and all in the portfolio page are without the alt atribute. If you see the code, it is something like
<img src='http://www.webpage.com/wp-content/uploads/2010/09/nutricion-saludable-200x130.jpg' alt='' title='Nutrición saludable' />
Could you please me help to get this atribute and add it in each image? Thank you for your support.
