Converting JPEG to BMP and other issues with Graphics

I was wondering why it is so difficult to find an easy solution using .NET Fremework 2.0 to convert JPEG image into BMP format (why there is a tone of examples to do BMP to JPEG convertion)

So here is my C# code, may be someone will find it helpfull

public static Image ConvertToBMP(Image source)
Bitmap result = new Bitmap(source.Width, source.Height, PixelFormat.Format32bppPArgb);

Rectangle rect = new Rectangle(0, 0, source.Width, source.Height);
using (Graphics g = Graphics.FromImage(result))
g.DrawImage(source, rect, 0, 0, source.Width, source.Height, GraphicsUnit.Pixel);

return result;


I didn't tested yet this for all image types, however for JPEG it works :)
