The problem looks you have put your php file in gallery folder...

/home/a9773555/public_html/gallery/index.php on line 2

if that is the case (if you put index.php in gallery) then try the following:

<?php
    foreach(glob('images/*', GLOB_NOSORT) as $image)   
    {  
        echo "Filename: " . $image . "<br />";      
    }  
?>

Or do the following,

Put your index.php in your /home folder. then...

<?php
    foreach(glob('a9773555/public_html/gallery/images/*', GLOB_NOSORT) as $image)   
    {  
        echo "Filename: " . $image . "<br />";      
    }  
?>

Give it a try. and let me know...
