imagegif函数linux下失败,windows下成功,为什么?
分别在windows下和linux下执行代码:($gif_app为图片路径名)
$img_app = imagecreatefromgif($gif_app);
echo "$img_app
";
if(imagegif($img_app,"../images/atopo.gif"))
  echo "success";
else echo "fail";

windows下成功的产生了图片atopo.gif

但linux下面执行结果为
Resource id #3 
fail

php版本是php-5.2.6-2.fc8
gd库版本是gd-2.0.35-1.fc8

请高手指教!
