Dumbledore, Aslan of Narnia and magical portraits

I think there are many similarities between the death of DD and 
Aslan, the great lion of Narnia, who is killed by the evil witch on 
the stone table in "The lion, The witch and The wardrobe". The lion 
also pleads with the witch to kill him, so that he can return 
stronger and more magical than ever. Same thing with the death of 
Gandalf in LOTR. 

Even though DD doesn't return from the dead, someone has surely 
painted his portrait to go with the paintings of the past head 
masters of Hogwarts. Won't that mean that he will be able to give 
Harry advises through his portrait, even for the future? It seems to 
me that the other portraits we have met in the books have quite a 
lot of carachter...

How do these magical portraits work, has anyone discussed this 
before? Must they be painted by a special artist while the person is 
still alive, maybe leaving some of his or hers sole in the portrait 
through a mini-horcrux? When reading of the woman Tom Riddle robbed 
for her antique treasures I immidiately thought of the portrait of 
the Fat Lady guarding the Gryffindor's common room, are they the 
same lady? They are both fat and pink...
