Oops. I didn't read far enough. I found the following in a
separate thread.
I don't know a way around the problem you're describing with your
version of PHP, but PHP 4.0.6 with GD 2.0.1 allows you to call
ImageCreateTrueColor(), which eliminates the 256-color limitation with
JPEG files-- solved my problem right away.

has this problem
check the annoted manual on php.net. i believe there is a work arround
posted on imagecolorallocate() and i reposted the same thing under
imagecreatefromjpeg. basically you create and image, allocate colors, and
then copy your jpeg on it.

Lets say I have a black JPEG-image and I want to add yellow text to it,
how can I define the yellow color?
According to the manual, you can only get closest value of your desired
color by letting the ImageColorClosest() find it. Therefore, if the
image is totally black, you can not get the
Could try this:
$blue = ImageColorAllocate($image, 0, 0, 255);
Substitue blue for yellow and you'll be the appropriate RGB values for the
numbers.

Thats the problem, if I do that and the color is not used before in the

Hmm, I create my image from scratch and haven't tried drawing on an existing

hmm.
If what I understand from your ImageColorClosest(); function, why don't you
just add yellow to the palette? that way it can be found by the function,
but isn't used in the image?
HTH,

Is this only a problem with PHP/GD versions previous to 4.0.6/2.0.1?
Does the new ImageCreateTrueColor() function fix this issue?

I'm not sure I follow. I know this is how I would do it if I had a
GIF-image, but this does not include JPEG. Thats the main issue. The
JPEG is saved as an RGB-image, not index colored like GIF, therefore I'm
asking about how to add a RGB color to a non-index-color-image (JPEG).

I believe the problem is GD previous to version 2.0.1... They could only
create images with indexed (256?) colors...
I had a PHP script that used GD to resize JPEGs to smaller thumbnails
automatically... And it would always reduce them to 256 colors, until I
upgraded to PHP 4.0.6, GD 2.0.1, and
