Newbie has his arrays flooding.

Hello. Trying to store a 640*480 image into an array.
I'm fairly sure there's a smarter way to do this, but I
would like to understand what I'm doing wrong. And
I expect it's a lot of things.
The source:
void setup(){
size(640, 480);
}
void muunna(){
BImage lahde_img;
lahde_img = loadImage("sota_bw.jpg");
int[][] img_palaset = new int[19200][16];
int i;
i = 0;
int i2;
i2 = 0;
int i_x;
i_x = 0;
int i_y;
i_y = 0;
int rbg;
rbg = 0;
int index;
index = 0;
BImage i_img = get(0,0,4,4);
while(i<=19199) {
while(i2<=15){
index = i_y*640 + i_x;
i_img.pixels[i2] = lahde_img.pixels[index];
if(i_x%4==0){
i_y = i_y + 1;
i_x = i_x - 4;
}
i_x = i_x + 1;
i2 = i2 + 1;
}
i_x = i_x + 4;
i2 = 0;
while(i2<=15) {
img_palaset[i][i2] = int(3 * red(i_img.pixels[i2]) + .6 * green(i_img.pixels[i2]) + .1 * blue(i_img.pixels[i2]));
i2 = i2 + 1;
}
i2 = 0;
i = i + 1;
}
I thank you in advance.
