This is my first time using GD. I've got an image with a transparent background. All the other pixels are the identical color (#8bc4ed). I want to replace all those pixels with a given color, say #CCC5AC. Here's my code that doesn't work yet:
$filepath = $_SERVER['DOCUMENT_ROOT'] . "/images/source_image.gif";
$image = imagecreatefromgif($filepath);
$indexToSearchFor = imagecolorat($image, 3, 0);
imagecolorset($image, $indexToSearchFor, 204, 197, 172);
$filepath = $_SERVER['DOCUMENT_ROOT'] . "/images/target.gif";
imagegif ($image, $filepath); The output image is identical to the input image - no color is replaced.
What is the correct way to do this?
Here is a link to the image I'm trying to change in case you can tell anything from it:

Thanks very much to all in advance for any info!
