How to save picturebox as JPG with Intel Lib and after using SetPixel??

I used the SetPixel method on an image modifying it a little. I now want to save the image as a jpeg using the Intel lib cause I do not know any other way of saving a jpg file from a picturebox.

I know how to save is as a BMP cause I save the Image, not the picture. But how about a JPG file or a GIF file? When i use the routine I have with the Intel Lib, the modifications I made with SetPixel are not saved. Any suggestions?

Thanks!

Nevermind, I just saved the modified image as a BMP, loaded it back in and re-saved it as a jpg with the intel lib.
