If Micro.blog doesn’t show your pictures from your WordPress site make sure your feed uses absolute paths. I edited wp-config.php:

define(‘WP_Content_URL’, ‘http://www.yoursite.com/wp-content’);

Thanks to @rosemaryorchard and @manton for helping me figure that out!

@rosemaryorchard It was! From what I read Wordpress used to use the absolute path, but my installation never did. Thanks.
