resizing jpg into png

[loll]

I have a script that takes photo size jpg's and displays them as thumbnails. the Thumbnails are in PNG format (altho the problem occurs if I use JPG too).

When its resized the image, the colours in the image are washed out and so the thumbnail is bearly recognizable.

Is there something that I can do to get the colours from the JPG stay in the picture once it has been resized?

the PHP code looks like this:

$new_w = ($img_width/4)-9;
$new_h = ($img_height/4) - 6;

header("Content-type: image/PNG");
$dst_img=ImageCreate($new_w,$new_h);

$src_img=ImageCreateFromJpeg("$img_name");

ImageCopyResized($dst_img,$src_img,0,0,0,0,$new_w,$new_h,ImageSX($src_img),ImageSY($src_img));

ImagePNG($dst_img);

[hand]

If possible try to use
ImageCopyResampled()
instead of
ImageCopyResized()

and tell us if you get a better result

Thanks for your help. After I read the user comments on that page I came across another function I had not used.

Instead of using:

$dst_img=ImageCreate($new_w,$new_h);

I used:
$dst_img=ImageCreatetruecolor($new_w,$new_h);

This fixed the colour problem 😃
