imagecopymerge() merging pallettes

[Echilon]

I'm using the following code in an image generation script.

$cnameshadowcolour = imagecolorallocate($bgimage, $shadowr, $shadowg, $shadowb);
imagettftext($bgimage, $cnamesize, 0, $cnameshadowinsx, $cnameshadowinsy, $cnameshadowcolour, $cnamefont, $cname);

The script has a number of different text strings that need to be written to it, aswell as a smiley that's copied using imagecopymerge(). All works perfectly when I have one text colour and the image, but once I add another colour with imacolorallocate(), the image becomes tinted with the colour of the font. If I create the image from one with a grey background, this problem doesn't happen, but when the background is either black/blue or the colours of the union jack, I get a tinted smiley.

I've run through loads of things to try and solve the problem, but I think it's happening because imagecopymerge(), the part that copies the second image onto the background, is merging the palletes. The problem only happens when I add the second text colour. Is there any way to stop this?

I had this problem once before, and I can't remem,ber how I fixed it.

The image as it should look

When I add the second text string, the colours becoms tinted.

can you post the hole code?
