[Plugin: Multiple Featured Images] Adding size breaks functionality

Hi Marcus,

I’m attempting to call your function like this:

<?php  echo '<a href="'.get_permalink().'">'.kd_mfi_the_featured_image( 'slideshow', 'post', 'full',
                    array(
                        'alt'	=> trim(strip_tags( $post->post_title )),
                        'title'	=> trim(strip_tags( $post->post_title )),

                    )).'</a>';
?>

It works until I add ‘full’ or any other custom size. Do you have any tips?

Love the plugin. Thanks for your time.
