Under PHP 4.0.4pl1 (for Windows) I can not start up old php_gd.dll from older PHP distribution. This is old GD library 3.0.12 that have GIF support. (Under 4.0.3pl1 everything was fine). Does anyone have idea about this problem Thanks in advance, Vladimir P.S. I installed and new ZendOptimizer for PHP. But I can not see that could be a problem?!?
