Saving an image in a picturebox - Please Help

[googie]

I need to open an image in a picturebox control, make changes to the image and save it. I have wrote code to do this, but when I pull up the saved image the changes are missing (ie. the image has reverted back to the previous image). Anyone have any thoughts?

What exactly are you doing? Are you using API drawing methods, Standard drawing methods...

How are you saving the picture? I may be able to help.
