Occasionally you get . or .. in which case you won't see a picture. If
your files are all .jpgs, try $files = glob("./gfx/zufall/*.jpg");
Alternatively try (untested):
$files = glob("./gfx/zufall/*");
shuffle ($files);
foreach( $files as $key=>$value){
if ($value=="." || $value==".."){
unset($files[$key]);
}
}
echo "<a href='index.php'><img src='".$file[0]."' height='341'
width='634' border='0'></a>";
}
?>
