I've solved my problems now.
I should press the button "Get Material", so I can change the material type from "Standard" to "Bitmap"~
Strictly speaking, Bitmap alone is not a material, it is a map. If u use Get Material and use bitmap, the so-called material cannot be use as a material for an object but, for example, the environment background only.
A material consists of difference components (channels) like: diffuse, specular color, specular level, ambient color, opacity, self-illumination, reflection, refraction, bump,......etc. You can change the values of some of the components (like the color of the diffuse component, the value of the opacity), or use maps (e.g. bitmaps or procedural maps) to control the variation of these components at differenct places, wherever a single color of value cannot satisfy your needs (e.g. u need a checker pattern of your material, so u use a checker bitmap or a checker procedural map in the diffuse component.) All these together makes a material.
