注意以下信息：
// Intraweb contains support for JPG files. To support GIF files, GIF support such as GIFImage
// must be installed into Delphi. The GIF support does not need to be compiled into the program
// at runtime, but must be loaded into Delphi so that TImageFile can properly display the GIF at
// design time.
//
// For more information on GIF support, please see the IntraWeb FAQ.
