..hehe and I wrote it wrong too. The first line still should be

bitmap.LoadFromFile('c:\1\2.bmp');

And now? Will you give any comment? Even if you store the bitmap in the first line it is still needed to rewind the stream before you can read what you wrote before...

God Ares,
  I am guessing that after the SaveToStream, you need to to do a seek to set the pointer back to the beginning of the stream. For Example:


bitmap.SaveToFile('c:\1\2.bmp');
Bitmap.SaveToStream(Stream);
Stream.Seek(0,0);
bitmap.LoadFromStream(stream);
bitmap.SaveToFile('c:\1\3.bmp');


Try this and lemme know how you make out, okay?

Good luck!!
