PNG's and Flash

programming flash
1

Why does this happen?(Ive never seen this problem before)

http://www.kinvault.net/LOTRO_bank/Lab/DJ/images/badpng.swf

when i load some pngs into a flash movie
here is the png
http://www.kinvault.net/LOTRO_bank/Lab/DJ/images/png-8passes.png
Note: PNG is created from php


$image = imagecreatefrompng($file_tmp);
                imagecopyresampled($image_p, $image, 0, 0, 0, 0, $width, $height, $width_orig, $height_orig);
                @unlink($filename);
                 imagepng($image_p,$filename);

so the png is valid but it loads into the swf as a red square
[edit] oh yeah heres my code

createEmptyMovieClip("_mc",1)
_mc.loadMovie(“http://www.kinvault.net/LOTRO_bank/Lab/DJ/images/png-8passes.png”)
