Thesis customizations I like

Making post images work with my multi-site installation

elseif ($type == 'thumb')
$image['alt'] = 'Thumbnail image for ' . get_the_title();
else

$open_link = '';
$close_link = '';
}
else {
$open_link = '[';
$close_link = '](' . get_permalink() . ' "Permanent link to ' . get_the_title() . '")';
}

$post_image['output'] = $open_link . '' . $close_link . "\n";
