Adding Images to a Winforms Project so They are Accessible as Resources

Buttons with images on are sometimes a lot easier to use than text based buttons - and can take up less space where it gets critical. But ... it can be confusing to get them into the app so they are available as Image objects directly, compiled into your app. So I thought I'd write it down for next time I have to do it so I - and maybe you - have an easier time.
