does this happen with jpgs or gifs (if you have support for
gifs)?
 [2001-07-24 21:43 UTC] design at barma dot lviv dot ua 
No, only with PNG, with JPG format working fine,
and i dont install GIF support, only standart installation of PHP 4.0.6

And - i copy php_gd.dll from PHP 4.0.5 in to PHP 4.0.6 directory - CopyResized working, but some GD function not working - PHP crashed.

PS Sorry for bad english, im living in Ukraine and dont have big language practic

Which version of GD do you have?
 [2001-07-25 03:47 UTC] design at barma dot lviv dot ua 
I use standart version of PHP, downloaded from www.php.net

i think in PHP 4.0.5 and 4.0.6 used GD 1.8.4
but in PHP 4.0.6 ChangeLog file i see some GD 2.0.1 function
 [2001-08-06 08:34 UTC] sniper@php.net 
This is a bug in the GD-2.0.1 (beta) library.
Closed.
