Custom size images error

Even though you can change the default image size for the menus, the function that pulls the image doesn’t use it.

The error resides in the function erm_get_image_src in file includes/misc-functions.php.

Around line 20 the function looks like this:

function erm_get_image_src( $image_id, $size = 'thumbnail' ) {

  if ( $size == 'full' || $size == 'large' || $size == 'medium' || $size == 'thumbnail' ) {
    $image_data = wp_get_attachment_image_src( (int)$image_id, $size );
    return $image_data[0];
  }
  return false;
}

It’s enough to remove the if to solve the problem
