Limit Images Random Order?

Is there a possible way to limit the number of images I return? I would also like to randomize their order. Here is the code I am using to list all of the tax images/terms.

<?php $terms = apply_filters( 'taxonomy-images-get-terms', '', array('taxonomy' => 'feature-title') );
	if ( ! empty( $terms ) ) { echo '<ul class="ft_tag_list">';
	foreach( (array) $terms as $term ) {
	echo '<li class="tag_list_item">';
	echo '<div class="tag_image"><a href="' . esc_url( get_term_link( $term, $term->taxonomy ) ) . '">' . wp_get_attachment_image( $term->image_id, '' ) . '</a></div>';
	echo '<div class="tag_name"><a href="' . esc_url( get_term_link( $term, $term->taxonomy ) ) . '">' . $term->name . '</a></div>';
	echo '</li>';
	  }
	echo '</ul>';
  }
?>
