My best guess is that you might have turned off Warnings (and Notices) and that the

$hometime= $Twitter->get_statusesHome_timeline();

call doesn't return any xml but "false" because it can't connect (or something).

Did you try printing $hometime after the call ?

$hometime should be an array of status objects.

Try

<?php
$hometimeline = $Twitter->get_statusesHome_timeline();
foreach($hometimeline as $status){
    echo '<div class="twitter_status">';
    foreach($status->user as $user){
        echo '<img src="'.$user->profile_image_url.'" class="twitter_image">';
        echo '<a href="http://www.twitter.com/'.$user->name.'">'.$user->name.'</a>: ';
    }
    echo $status->text;
    echo '<br/>';
    echo '<div class="twitter_posted_at"><strong>Posted at:</strong> '.$status->created_at.'</div>';
    echo '</div>';
}
