note 59169 added to function.imagecreatefromgif

Im having this serious problem. I am using PHP 4.3.9 Installer for windows, installed successfully, now i want to use ImageCreateFromGIF to perform a simple image management action to set transparency of GIF images background. I have Gif images in a dir to which i wanted to send a browser a transparent background gif. At present background is white. But i wonder why is it not happening. Do i have to install GD Lib dll seperately or is this feature is bundled in win32 installer for ver 4.3.9 of php. Thanks in advance to a guru who can guide this newbie. regards: ---- Manual Page -- http://www.php.net/manual/en/function.imagecreatefromgif.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+59169 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+59169&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+59169&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+59169&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+59169&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+59169&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+59169&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+59169&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+59169&report=yes Search -- http://master.php.net/manage/user-notes.php
