Okay, so this little script is put seperately in your directory, then you can access it using CSS, or an image html tag. The idea is mainly for a web banned. This is the script i used on Lindrian's website.

Example:
Anyways, i did use tutorials to help create this so i guess not all creedit to myself! but to w3schools too (and another i can't remember) lol.
To use:
<img src="gradient.php?start=START_HEX_COLOR&end=END_HEX_COLOR" />
That's all there is to it! Although, you can play around with the height and widths and all! The default gradient is set at black-white. to change it, simply add the start and end variables
<?php
header("Content-type: image/png");
$height = 100;
$width = 50;
$start = '000000';
$end = 'FFFFFF';
if ($_GET["start"]) {
$start = $_GET["start"];
}
if ($_GET["end"]) {
$end = $_GET["end"];
}
$start_r = hexdec(substr($start, 0, 2));
$start_g = hexdec(substr($start, 2, 2));
$start_b = hexdec(substr($start, 4, 2));
$end_r = hexdec(substr($end, 0, 2));
$end_g = hexdec(substr($end, 2, 2));
$end_b = hexdec(substr($end, 4, 2));
$image = @imagecreate($width, $height);
for($y=0;$y<$height;$y++) {
for($x=0;$x<$width;$x++) {
if ($start_r == $end_r) {
$new_r = $start_r;
}
$difference = $start_r - $end_r;
$new_r = $start_r - intval(($difference / $height) * $y);
if ($start_g == $end_g) {
$new_g = $start_g;
}
$difference = $start_g - $end_g;
$new_g = $start_g - intval(($difference / $height) * $y);
if ($start_b == $end_b) {
$new_b = $start_b;
}
$difference = $start_b - $end_b;
$new_b = $start_b - intval(($difference / $height) * $y);
$row_color = imagecolorresolve($image, $new_r, $new_g, $new_b);
imagesetpixel($image, $x, $y, $row_color);
}
}
imagepng($image);
imagedestroy($image);
?>

A live example can be found in the above link. just add "start" and "end" values
