tridion 2009 - copy multimedia component from one publication to another

Question

How do I copy a image component, from one publication to the other using api's in 2009?

Is this possible? I tried using

    newComponent.Multimedia.SetUploadedMultimediaFilename(originalComponent.Multimedia.Filename);

+newComponent.save(); where my newComponent is the one that I am creating from the original component.

That won't work... you'll need to first save the multimedia item to a file location, then use this location to upload it from. All you're doing now is telling Tridion that there is a file at originalComponent.Multimedia.Filename which may or may not be true.
