Each image you upload to the media library uses the filename before the extension as it's slug. You can use the get_posts function and pass in $dayofyear:

  function get_attachment_url_by_slug( $slug ) {
  $args = array(
    'post_type' => 'attachment',
    'name' => sanitize_title($slug),
    'posts_per_page' => 1,
    'post_status' => 'inherit',
  );
  $_background = get_posts( $args );
  $background = $_background ? array_pop($_background) : null;
  return $background ? wp_get_attachment_url($background->ID) : '';
}

That will return the ID of the image you're trying to get by it's slug.

If you're doing this inside a page or post template, you would use:

$dayofyear = date('z');
$background_url = get_attachment_url_by_slug($dayofyear);

Then set the inline style of the element, for example:

<div style="background-image: url(<? php echo $background_url; ?>);"></div>

This won't work if you're trying to inject this into a stylesheet.
