Im trying to use dynamic buttons, and Im trying to figure out how to get
around the header call.
I figure use output buffering, but so far Ive only come up with errors.
Anyone see a better way or any errors in my code.
Thanks
nb: Uncomment the echo() statement to get the error.

<?php
//echo 'Hey<br>';
function button($word) {
ob_start();
header("Content-Type: image/png");
$im = ImageCreate(100, 50);
$black = ImageColorAllocate($im, 0, 0, 0);
$white = ImageColorAllocate($im, 255, 255, 255);
$start_x = 50 - (strlen($word) * ImageFontWidth(5) / 2);
$start_y = 25 - ImageFontHeight(5) / 2;
ImageString($im, 5, $start_x, $start_y, $word, $white);
ImagePNG($im);
ImageDestroy($im);
ob_end_flush();
}
button('Hello World');
?>
