Loading in folder outside of my sketch's data folder (processing) - processing

Question

Im sure there is a pretty straight forward answer to this...cant quite figure it out though.
In my processing sketch's data folder, there is a folder named test_segments. test_segments contains a bunch of images.
I need to load an image from test_segments into my PImage.
It looks like this: http://imgur.com/a/iG3B6
My code:
final int len=25;
final float thresh=170;
boolean newDesign=false;
PImage pic;
ArrayList<PImage> imgContainer;
int n=3;
void setup() {
size(800, 800, P2D);
colorMode(RGB, 255);
background(250, 250, 250);
rectMode(CENTER);
//imageMode(CENTER);
pic=loadImage("hand.jpg");
pic.resize(width, height);
color c1 = color(200,25,25);
color c2 = color(25, 255, 200);
imgContainer=new ArrayList<PImage>();
PImage pimg1=loadImage("this is where test_0.png needs to go")
pimg1.resize(50, 50);
imgContainer.add(pimg1);
noLoop();
noStroke();
}
void draw() {
if (newDesign==false) {
return;
}
pic.loadPixels();
for (int y = 0; y < height; y+=40) {
for (int x = 0; x < width; x+=40) {
int index=y*width+x;
color pixelValue = pic.pixels[index];
color rgb = pixelValue;
int r = (rgb >> 16) & 0xFF; // Faster way of getting red(argb)
int g = (rgb >> 8) & 0xFF; // Faster way of getting green(argb)
int b = rgb & 0xFF;
//How far is the current color from white
float dista=dist(r,g,b,255,255,255);
//50 is a threshold value allowing close to white being identified as white
//This value needs to be adjusted based on your actual background color
//Next block is processed only if the pixel not white
if(dista>30){
float pixelBrightness = brightness(pixelValue);
float imgPicked=constrain(pixelBrightness/thresh, 0, n-1);
image(imgContainer.get((int)imgPicked),x,y);
}
}
}
}
void mouseReleased() {
newDesign=!newDesign;
redraw();
}
Thanks!

You should just be able to do:
PImage pimg1 = loadImage("test_segments/test_0.png");
If that doesn't work, please try to post a MCVE like we talked about before. Here's an example of an MCVE that would demonstrate your problem:
PImage pimg1 = loadImage("test_segments/test_0.png");
image(pimg1, 0, 0);
Don't forget to include exactly what you expect to happen, and exactly what's happening instead. Good luck.
