Saving Images

Hi, I am looking for a way to save images to a DataSet. I have read the following article: http://www.c-sharpcorner.com/Code/2002/Feb/FlashCardsMG.asp I would like to save an image by getting it directly from a PictureBox rather than using a FileStream on the image's file name. How would I do this? I also am wondering if it is possible to load an image directly from a DataSet into a PictureBox without creating an actual file on my PC? Thanks a million.
