When I run this code I get the following error:
The image "http://siteprevue.net/flipit.php" cannot be displayed because it contains errors.
I'm thinking... of course it can't be displayed, it's a url not an image... duh?!
Everything executes fine, I just get this black page that thinks the url is an image.
This happens on (some) other GD2 coded pages as well, but not all.
Does anyone have any idea what's happening?
<?php
$src = '../../Uploads/Gallery/drafting_site_bg_200.jpg';
$new_img = '../../Uploads/Gallery/copy_bg_200.jpg';
$image = imagecreatefromjpeg($src);
$image = flip($image,1,0); // flips horizontal
//$image = flip($image,0,1); // flips vertical
//$image = flip($image,1,1); // flips both
header("Content-type: image/jpeg");
imagejpeg($image, $new_img, 80);
imagedestroy($image);
function flip($i,$h=1,$v=0) {
$width = imagesx($i);
$height = imagesy($i);
$temp = imagecreatetruecolor($width,$height);
imagecopy($temp,$i,0,0,0,0,$width,$height);
if ($h==1) {
for ($x=0 ; $x<$width ; $x++) {
imagecopy($i, $temp, $width-$x-1, 0, $x, 0, 1, $height);
}
imagecopy($temp,$i,0,0,0,0,$width,$height);
}
if($v==1) {
for ($x=0; $x<$height ; $x++) {
imagecopy($i, $temp, 0, $height-$x-1, 0, $x, $width, 1);
}
}
return $i;
}
?>

With this line
header("Content-type: image/jpeg");
you are telling the browser that the data he receives after this was that of a JPEG image – so if you’re not intending to send image data after that, that line has no place being there.
Simply remove it, so that PHP will send its default Content-Type text/html again.
