C# .jpg help pls

Can i get some help?
I am making a program in c# that hides strings into images by changing each pixel color to be odd or even so i can store binary data in the pixels without changing the over all look of the image. Its just something i am making for fun but it only seems to work with .bmp's. I want to get it working with .jpg but i dont know how to do this. Right now i am just using System.Drawing.Bitmap to modify the images. Is their any other way that i can do this so it will be compatible with .jpg?

That was the worst code i've ever seen. No indentation, no order, only one comment.
