Change quality of image

[Hamlets666]

[code]$neww=40;
$newh=40;
list(, , $type,)=@getimagesize($file);
if ($type==1) {$funci="imagecreatefromgif";} //$funco="imagegif";}
if ($type==2) {$funci="imagecreatefromjpeg";} //$funco="imagejpeg";}
$im1 = @$funci($file);
$im2=@ImageCreate($neww,$newh);
@imagecopyresized($im2, $im1, 0,0,0,0,$neww,$newh, @imagesx($im1), @imagesy($im1));
@header("Content-type: image/png");
@imagepng($im2);[/code]

It`s code which changes image size(pixels), but after this image size(kb) is still too big for me, so are there any ideas, how could I change quality of image?

You could save the image as a jpeg and use the third parameter of the imagejpeg function to control the compression. Or do you specifically require your images to be png?

They can be gif, only if it will make them smaller  :)
Quality can be very bad it would be o.k  ;D
