<?php

$header_thumbs = get_posts(' $args&category_name=events&posts_per_page=4');
if( $header_thumbs ) :
  foreach( $header_thumbs as $header_thumb ) {
  setup_postdata($header_thumb);

  echo '<a href="' . get_permalink($header_thumb->ID) . '">' . get_the_post_thumbnail($header_thumb->ID) .   '</a>';
