Drupal 7，iPhone图像方向混乱-没有exif信息

所以，这两天来，我一直在发疯。我有一个基于Drupal7的网站

我遇到的问题是，当我的网站用户从iPhone或iPad上传图像时（通过ckeditor和通过表单上传的账户档案图像），图像最终会被颠倒过来

当我注意到一个奇怪的问题时，我甚至编写了独立的php来读取图像的exif数据并检测问题。图像在不在drupal中时确实有exif信息，而且一旦上传到drupal，它们似乎就会丢失exif信息

我使用此代码读取exif信息

$full_filename ='image.jpg';
$exif = exif_read_data($full_filename);

print "<pre>";
    print_r($exif);
print "<pre>";

这是上传到drupal的图像中的信息

有没有可能drupal与此有关。GD工具包

我试着使用imagecache autorotate，它可以旋转不是从iphone上传的图像，但在ipad或iphone上没有

我不知道该如何开始。欢迎所有帮助。

您没有看到任何东西

iPhone/Pad在发送图像时会删除EXIF信息

EXIF自定义模块可能会有所帮助

ImageCache操作也可能如此
