我的Web应用程序运行在开发服务器，租用的物理服务器和Azure VM上。开发服务器和Azure服务器可以完美运行ImageResizer，但是Win2K12上租用的服务器在resizer.debug中存在以下错误：
The FreeImage library is not available! All FreeImage plugins will be disabled.
我尝试删除FreeImage.dll并下载它，这已经成功完成了，但是仍然出现错误。
我真的被可能导致这种情况的原因所困扰。这是权限问题吗？很抱歉，文档中的某个地方已覆盖该文件，因为我找不到它。
以下完整的resizer.debug信息：
