XP read/write problem (I guess)

<?php
$handle = opendir('covers');
$filename=0;
while (false !== ($filename = readdir($handle)))
{
$str=str_replace(".jpg", "", $filename);
if (is_numeric($str)) //all pics are of the digitdigitdigit.jpg
style
{
$size = getimagesize("./covers/$filename");
$src_width = $size[0];
$src_height = $size[1];
$dest_height = 100;
$dest_width = $dest_height*$src_width/$src_height;
$src_img = imagecreatefromjpeg("./covers2/$filename");
$dst_img = imagecreatetruecolor($dest_width,$dest_height);
imagecopyresampled($dst_img, $src_img, 0, 0, 0, 0,
$dest_width, $dest_height, $src_width, $src_height);
imagejpeg($dst_img, "./thumbs/$filename");
imagedestroy($src_img);
imagedestroy($dst_img);
}
}
?>

1) Does this thumbing function look ok for its purpose?
2) If I echo $filename at each loop, I see the function DOES scan all
my jpg files but no thumb is created
I tried to attrib -R my folders, to no avail :'S

Any leads or pointers?

Thanks,

Sebastian

the result of str_replace() is a string representing a number but being
not a number. So is_numeric() always returns FALSE.
change your test criteria.
