Embedded Resources, ImageLists
Discovered that images added to a project can have their build property set to “Embedded Resource”.
You can then get at them programmatically by:
Image.FromStream(Assembly.GetExecutingAssembly().GetManifestResourceStream("SharksEye.VisionVest.Resources.image_medium.ico"));
And then I learned that images added to an ImageList using the Visual Studio IDE are converted to embeded resources.
