Stop 'alt' from being added to the_post_thumbnail

Question

I'm using the_post_thumbnail to display a specific thumbnail size. The function outputs an 'alt=' tag with the description of the attachment. Is it possible to clear the value in the ouput? So it'll display alt=""?

Answer 1

If you look here: http://codex.wordpress.org/Function_Reference/the_post_thumbnail you will see that you can change the alt. You have to add an array with the value for the alt in the second parameter like so: <?php the_post_thumbnail('thumbnail', array( 'alt' => false )); ?>
