When the code is compiled, can you see a dots in front of executable lines,

in procedures listed below?

These procedures do the following:

1)

TPicture.RegisterFileFormat('gif','Gif Image',TGifImage);

Associates 'gif' extension with TGIFImage.

You got an error message because the extension is not associated

2) procedure MyCreateGraphic and assignment RV_CreateGraphics :=

MyCreateGraphics;

Workaround for Delphi/TGIFImage bug.

3)

procedure MyAfterImportGraphic and assignment RV_AfterImportGraphic :=

MyAfterImportGraphic;

Turns off animation in loaded gifs (animation is not supported)
