saving picturebox.image as 24bpp bitmap

[jamesjames]

Hello, could anyone tell me how to save a bitmap from picturebox.image as a 24bpprgb bitmap?

picturebox.Image.Save(path, ImageFormat.Bmp) saves a 32bpprgb bitmap

and

Bitmap bmp = (Bitmap)picturebox.Image; gets a 32bpprgb bitmap too.

So is it possible at all?
