What is the best type to use for returning an image in my C# library project?

Question

I'm making a project that will scrap information about a movie and return all sorts of goodies. This will be a .dll that other developers will use in their projects.

For example, if they want to set a pictureBox image to the movies poster, what would be the best way to handle my library returning the image?

//Set the image to The Matrix poster.
pictureBox1.Image = MyLibrary.GetPoster("The Matrix");

Should I return an Image? A Byte[] array?

Answer 1

I would say return a System.Drawing.Image.

Answer 2

Return an image.

Answer 3

I think returning System.Drawing.Bitmap makes it easy to use
