What is the best way to deal with Image buttons?

I have some image buttons on a form and am interested in how others have handled some of the issues:

1.  What is the best way to "store" the image within the form?  Currently I am loading a bitmap but these bitmaps need to be on a directory that is independent from the program.  It would be nice if the images could be stored within the form.  Is there a good way to do this?

2. What is the best method for dealing with image button images?  There is an "up" image, a "down" image, and a "deactivated" image for each button.

3. Is there a better way of dealing with image buttons than to use "images"?

Thank you in advance.
