PNG files not showing in PHP download script

like always ... IE should be having some stupid rules to make coders work more ...

i am using a PHP class to server files from the server (ex : http://site/downwload.php?id=5) will download file that has id=5 ...

everything works just gr8 ... except PNG images 开发者_JAVA技巧on IE !!! works perfect on all other browsers ...

Any clue guys ?

Thank you .

Do you send any header that with content type? I can be a problem if you only send the data without the content type header.

header('Content-Type: image/png');
readfile('path/to/myimage.png');

Found it ,

IE doesn't like the Content-Range and Content-Length headers for png images ...
