it's because setup() is not the right place for your image() statement:
put it inside a loop() or a draw() and it'll work...

also what is that draw()?
I cant seem to find it.........
another questions
1> the Network code seems doesnt work in my version...it's for newer version right?
2> setPixel.....and other drawing codes......
if I put it in the loop(), it seems it must redraw in the next loop........
what if I only want things to be drawn once so that the comptuer need not repeat drawing all the time?

hi betaruce, please read the reference guide first to better understand the basic structure of a Processing program. setup() and loop() are explained in detail here.
as for drawing objects only once: you can use a draw() function which will be executed only once (to create a static image). if draw() is used, the loop() block will not be executed.
if you do wish to have continuous updates, but do want to keep things drawn previously you can disable the automatic clearing of the screen by calling noBackground() within the setup() code block. in this mode you can also draw things within the setup() function...
re: network code - which version are you using? you didn't tell us... plus what did you try to do? 
answers need details!

Mine is 0053.
For the load image, I still cannot load, no matter in setup(), loop() or draw().
But I'm quite sure that my code is correct and the pic is in the data folder.

I am on 0056, and this code works:
BImage b;
void setup(){
size(200,200);
background(255);
}
void loop(){
b = loadImage("bg.jpg");
image(b,0,0);
}
I placed a picture called "bg.jpg" in the data folder, which is 200x200 pixels.
If you can't get i working, maybe you should try and download ver. 0056 instead?
...uhh, and this works aswell:
BImage b;
void setup(){
size(200,200);
background(255);
}
void draw(){
b = loadImage("bg.jpg");
image(b,0,0);
}
However, in the latter (as stated above) you cannot use the loop() method, since this is ignored as soon as you use the draw() methods!
