How can the code be modified to ensure that the thumbnails are displayed correctly for all images in the "bilder" directory?

The issue could be resolved by ensuring that the file path for each image includes the "bilder" directory in the src attribute of the img tag. This can be achieved by concatenating the directory path with the image file name in the loop that generates the thumbnails. 

<?php
$images = glob("bilder/*.jpg");
foreach ($images as $image) {
    echo '<a href="' . $image . '"><img src="' . $image . '" alt="thumbnail"></a>';
}
?>
