Calling function which has header()

[Anon]

I have the following function stored in a function.php file which is included for every page on a site:

function MenuImage ($image, $words) {
header("Content-Type: image/png");

$im = @ImageCreateFromPng($image);
if ($im == "") {
echo "error - image missing";
} else {

$white = ImageColorAllocate($im, 255, 255, 255);
ImageString($im, 3, 6, 4, $words, $white);
ImagePng($im);
ImageDestroy($im);
return $im;
}

}

Which I call using:

MenuImage("images/menuimg.png", "Services")

at certian places in the script. the only problem is that I need a workaround for the 'headers already set' problem. I realize that all headers must be called before any HTML but this function requires that the header be set for the image... is this correct? and any suggestions on how to fix it?

Why on earth would you be sending ANY html in a script that appears to be designed to send PNG graphics? I don't get it.

rethink how you're calling the function.

Assuming you're creating a menu, have your main php script call another php script to actually show images. for example replace menuimage function with <IMG SRC="display_image.php?image=images/menuimg.png&words=Services">. In your display_image.php page call the menuimage function to show the image.
