cyklus a pole

kod:

<?
$dir = "./fotky/";
$subdir = opendir("$dir");
while ($file = readdir($subdir)) {
$obr = "$dir$file";
$size = getimagesize($obr);
$width = $size[0];
$height = $size[1];
$pole = array (
"$i" => array (
"show" => "<img border=\"0\" src=\"$obr\" width=\"$width\" height=\"height\">",
"width" => "$width",
"height" => "$height",
"name" => "$obr"
)
);
++ $i;
echo $pole ["10"] ["name"].'<br>'; // toto sa zobrazi
}

echo $pole ["10"] ["show"]; //toto sa uz nezobrazi. PRECO?
?>
