每12张图片的PHP div

Question

i have this piece of code:

<?
include( "http://api.flickr.com/services/feeds/photos_public.gne?id=22352410@N07&lang=en-us&format=php" );
$i = 0;
    foreach($feed['items'] as $item) {
    preg_match("/<img src=\"([^\"]+)\" .*? \/>/", $item['description'], $matches);
    $img_html = $matches[0];
    $img_src = $matches[1];
    $medium_url = ereg_replace("_m", "_s", $img_src);
        echo "$img_html";
    }

?>

How I could make that each N number of pictures appear inside of a <div></div> Example:

<div class="container">
<img src="1.jpg" /> 
<img src="2.jpg" /> 
<img src="3.jpg" /> 
<img src="4.jpg" /> 
<img src="5.jpg" /> 
<img src="6.jpg" /> 
<img src="7.jpg" /> 
<img src="8.jpg" /> 
<img src="9.jpg" /> 
<img src="10.jpg" /> 
<img src="11.jpg" /> 
<img src="12.jpg" /> 
</div>
<div class="container">
<img src="13.jpg" /> 
<img src="14.jpg" /> 
<img src="15.jpg" /> 
<img src="16.jpg" /> 
<img src="17.jpg" /> 
<img src="18.jpg" /> 
<img src="19.jpg" /> 
<img src="20.jpg" /> 
<img src="21.jpg" /> 
<img src="22.jpg" /> 
<img src="23.jpg" /> 
<img src="24.jpg" /> 
</div>

etc...

Any Ideas??

Thanks so much!!!

About the double div: Move the if statement, that checks whether there is a remainder down, below the statement that increments the counter, and it will not create the double div:

<?
include( "http://api.flickr.com/services/feeds/photos_public.gne?id=22352410@N07&lang=en-us&format=php" );
$i = 0;
echo "<div class='container'>";
foreach($feed['items'] as $item) 
{
     preg_match("/<img src=\"([^\"]+)\" .*? \/>/", $item['description'], $matches);
     $img_html = $matches[0];
     $img_src = $matches[1];
     $medium_url = ereg_replace("_m", "_s", $img_src);
     echo "$img_html";
     $i++;
     if($i % 12 === 0)
          print "</div><div class='container'>";
}
print "</div>";
?>
