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
