I somehow solved that myself.
The problem is, that TweetPress does not create a post for every image it uploads.
So what i did is, insert this code inside tweetpress.php:
// Create post object
$my_post = array();
$my_post[‘post_title’] = “”;
$my_post[‘post_content’] = $_POST[‘message’].'<img class=’.'”‘.”alignnone size-medium wp-image-10″.'”‘.” src=”.'”‘.$imageurl.'”‘.”/>”;
$my_post[‘post_status’] = “publish”;
// Insert the post into the database
wp_insert_post( $my_post );
and voila, every TweetPress image has a post with an URL to the image, so autofocus will find it.
Still some tweaking to go, but what i am looking for is there 😉
Maybe someone of you could use it as well
Best
