Nor this
var
jpeg: TJPEGImage;
r: TBitmap;
begin
r := TBitmap.Create;
r.assign( Image1.Picture.Bitmap );
neither:
var
jpeg: TJPEGImage;
r: TBitmap;
begin
r := TBitmap.Create;
jpeg:= TJPEGImage.Create;
jpeg.assign( Image1.Picture.Bitmap );
r.Assign( jpeg );
does not work!

If you have loaded a jpeg into Image1.Picture there isn't any
Image1.Picture.Bitmap object to fetch as the .Graphic is a TJPEGImage. When
you access Image1.Picture.Bitmap a new, empty, bitmap will be created and
the jpegimage will be gone.
Try
r := TBitmap.Create;
r.Assign(Image1.Picture.Graphic);
instead. This should work with any type of graphic (bitmap, jpegimage,
pngimage, etc.)
