You just have to realize that the handle for an image, such as a field in a type, is just an integer which stores the memory address for the image, NOT the image data itself. If you say handle=LoadImage("image.bmp") "handle" is just a number. Similarly, writing My\graphic=LoadImage("image.bmp") just puts a number in "My\graphic." When you delete a type you are just removing the number.
Note that there are certain commands which wipe all graphics from memory so when you do that you don't have to deliberately free the graphics. For example, for 3D graphics you just call ClearWorld and then Delete Each [type.]
