What role does the "$zaehler" variable play in the code snippet, and how does it impact the output of the image links?

The "$zaehler" variable in the code snippet is used as a counter to keep track of the number of image links printed on the page. It is incremented each time an image link is printed. This variable ensures that only a certain number of image links are displayed per row, as specified by the condition in the code. 

$zaehler = 0;
foreach ($images as $image) {
    if ($zaehler % 3 == 0) {
        echo "<div class='row'>";
    }

    echo "<div class='col'><img src='$image' alt='Image'></div>";

    $zaehler++;

    if ($zaehler % 3 == 0) {
        echo "</div>";
    }
}
