Why I draw an png image using glDrawPixels() can't work well?

Bind order, draw order? You only bind one texture inside your example code.

Binding the texture just sets the opengl state. Its like taking a key for the lock.
Actually i don't know if the bind method will enable GL_TEXTURE_2D by itself. Just give it a try, but you might not want to depend on it.

I can post an example when i'm home. MAybe that will make some things more clear
