I am trying to have a title and alt for the default images that come with the mockup for corporate clean. I cannot get anything to work. Can someone please point me in the right direction as I am new to all of this?

this is the line of code for the image:

img class="masked" src="

<?php
print base_path() . drupal_get_path('theme', 'corporateclean') ;
?>
/images/products.jpg"/>
?>
