New Comment:

Are you sure there is no whitespace before the <?php-tag???

And if that's not the case, can you try the latest snapshot or at least 4.0.6?

Example:

$im = imageCreateFromPNG( "test-ob.png" );
ob_start();
imagePNG( $im );
$outbuffer = ob_get_contents();
ob_end_clean();
header( "Content-Type: image/gif" );
print $outbuffer;

(test url: "http://www.osd.dk/test/test-ob.php")

The script above will fail on the "header( ..." line stating that output has already been
sent and thus no more headers can be added.

For some reason the imagePNG() function (and other image output functions) seems to end the header
section of the output even though output buffering is active.

I'm currently unable to test this on a newer version of php.

Tais M. Hansen
