Create the image you are going to watermark with as a PNG, png
doesn't suffer the issues of the antialiasing issues like GIF.
You just want to make sure you use the function:
imagealphablending();
On the original image before you apply the watermark in your merge.
$image = imagecreatefromjpeg($source_file);
imagealphablending($image, true)
$watermark = imagecreatefrompng($watermark_file);
and then just do your imagecopymerge() normally
HTH,

Curt:
First, thanks for helping.
Second, I wasn't using a GIF -- my copyright was a png and my image was a jpg.
Third, the following is my code, I think I'm following what you said
-- but something is wrong -- the problem remains as shown here:
http://xn--ovg.com/watermark3
--- code follows ---
<?php
$original=imagecreatefromjpeg("mydog.jpg");
imagealphablending($original, true);
$watermark=imagecreatefrompng("copyright.png");
$osx=imagesx($original);
$osy=imagesy($original);
$wsx=imagesx($watermark);
$wsy=imagesy($watermark);
imagecopymerge($original, $watermark, ($osx-$wsx)/2, ($osy-$wsy)/2,
0, 0, $wsx, $wsy,100);
imagepng($original, "trans.png");
?>
