Hi,
I'm used the code below from Seanf (running with GD). It gave me thumbnail OK with full colors; but if I change $max_width = 120; and $max_height = 100 (since I want larger thumbnail), most colors in the image will be lost. What's to do?

Thanks,
John
PHP Code:
<?php

$image 
'coverr.jpg';
if (!
$max_width)
  
$max_width 80;
if (!
$max_height)
  
$max_height 60;

$size GetImageSize($image);
$width $size[0];
$height $size[1];

$x_ratio $max_width $width;
$y_ratio $max_height $height;

if ( (
$width <= $max_width) && ($height <= $max_height) ) {
  
$tn_width $width;
  
$tn_height $height;
}
else if ((
$x_ratio $height) < $max_height) {
  
$tn_height ceil($x_ratio $height);
  
$tn_width $max_width;
}
else {
  
$tn_width ceil($y_ratio $width);
  
$tn_height $max_height;
}

$src ImageCreateFromJpeg($image);
$dst ImageCreate($tn_width,$tn_height);
ImageCopyResized($dst$src0000,
    
$tn_width,$tn_height,$width,$height);
header("Content-type: image/jpeg");
ImageJpeg($dstnull, -1);
ImageDestroy($src);
ImageDestroy($dst);

?>
