MakePictures allows you to drop a picture on the window and it will convert it to a Xojo string that can be loaded into a constant. This will enable you to not have any pictures in your Resources folder and, therefore, keep them private within the application.

In addition you can load a folder of the icons (pictures) that are used within your application and create a Module that is a complete list of all the pictures with a text representation. The Module also includes a PictureFromString method that returns a Xojo picture.
