This works...

$first = array(
    22 => array(
        'ID' => 22,
        'post_author' => 1
    ),
    23 => array(
        'ID' => 23,
        'post_author' => 1
    )
);
$second  = array(
    array(
        'img_thumb' => 'small_duck.jpg',
        'img_full' => 'duck.jpg'
    ),
    array(
        'img_thumb' => 'small_fish.jpg',
        'img_full' => 'fish.jpg'
    )
);

echo '<pre>';
var_dump($first);
var_dump($second);

$i=0;
$should = array();
foreach ($first as $key => $arr) {
    if(isset($second[$i]))
        $arr = array_merge($arr,$second[$i]);

    $should[$key] = $arr;
    $i++;
}

var_dump($should);
