Adding classes, data attributes and removing links.

[nwtech]

Is there a way to apply a data attribute to images? I'm currently getting taxonomy images inside my loop with this:

echo apply_filters( 'taxonomy-images-list-the-terms', '', array(
    'after' => '</ul>',
    'after_image'  => '</li>',
    'before' => '<ul class="project-services">',
    'before_image' => '<li>',
    'image_size'   => 'portfolio-showcase',
    'taxonomy'     => 'services',
) );

On that same topic, I need to also add a class to the images. I tried the following to add attributes and a class, but with no success:

echo apply_filters( 'taxonomy-images-list-the-terms', '', array(
    'after' => '</ul>',
    'after_image'  => '</li>',
    'attr' => array(
        'class' => 'filter-tint',
        'data-pb-tint-opacity' => '1',
        'data-pb-tint-colour' => '#fff',
    ),
    'before' => '<ul class="project-services">',
    'before_image' => '<li>',
    'image_size'   => 'portfolio-showcase',
    'taxonomy'     => 'services',
) );

Is it also possible to remove the links from the images?
