All Images not calling alt text

You’re not outputting any attributes besides the src and class. Try using the_post_thumbnail() instead.

<?php the_post_thumbnail( 'post-thumbnail', array( 'class' => 'img-responsive' ) ); ?>

This will include all attributes and supports responsive image markup by default.
