Here's the image i used to get when i tried using built-in GD library
in PHP 4.3.1:
http://www.abcda.com/upload/thumb-lyonchik22.jpg1045676715.jpg
Same generated thumbnail, but with PHP 4.3.2RC1 built-in 2.0.11 GD:
http://www.abcda.com/upload/thumb-lyonchik22.jpg1045677288.jpg
And i just downloaded the new PHP 4.3.2RC2 and compiled it with the
same options i used when i compiled PHP 4.3.2RC1, and here's what i get
when it generates a thumbnail:
http://www.abcda.com/upload/thumb-lyonchik22.jpg1051596060.jpg
the function i posted here does everything in the script.
I just upload an image and call this function and it uploads the
selected image and generates a thumbnail from it.

Can you please try to com eup with a short script that doesn't depend
on anything else but the script (and of course an image) so that we can
copy and paste it from this bugreport? Please provide an URL to the
image as you obviously can not paste it onto this bugreport.

I am generating a thumbnail from a submitted image and i get a broken
image, the colors there are inadequate.
Here's the code i use:
function ImageName () {
if($_FILES['userfile']['type']!='image/gif' &&
$_FILES['userfile']['type']!='image/jpeg' &&
$_FILES['userfile']['type']!= 'image/pjpeg' ||
!isset($_SESSION['SESSION_UNAME'])){
return '';
} else {
$time = time();
switch($_FILES['userfile']['type']) {
case 'image/gif':
$newname = './upload/' . $_FILES['userfile']['name'] . $time .
".gif";
if(!copy($_FILES['userfile']['tmp_name'],$newname)) {
echo "Can't copy";
}
$newname = $_FILES['userfile']['name'] . $time . ".gif";
break;
case 'image/jpeg':
case 'image/pjpeg':
$newname = './upload/' . $_FILES['userfile']['name'] . $time .
".jpg";
if(!copy($_FILES['userfile']['tmp_name'],$newname)) {
echo "Can't copy";
}
$im = @ImageCreateFromJPEG($newname);
$im_X = ImageSX($im);
$im_Y = ImageSY($im);
$ThumbSize = getthumbSize($im_X,$im_Y);
$im_thumb = ImageCreate($ThumbSize['x'],$ThumbSize['y']);
ImageCopyResized($im_thumb,$im,0,0,0,0,$ThumbSize['x'],$ThumbSize['y'],$im_X,$im_Y);
$thumb_name = './upload/thumb-' . $_FILES['userfile']['name'] .
$time
. ".jpg";
ImageJPEG($im_thumb,$thumb_name);
$newname = $_FILES['userfile']['name'] . $time . ".jpg";
break;
}
return $newname;
}
}
this same thing happened in PHP 4.3.1, then it was fixed in PHP
4.3.2RC1, now it's present in PHP 4.3.2RC2 again...
I think it has to do with the new version of built-in GD library 2.0.12
against 2.0.11 in PHP 4.3.2RC1
