Problem using SCAD file

I am having a problem trying to gett a scad file to work

I have a directory on my desktop named SCAD that I put all the scad files in for easy access.
I am trying to use a lithophane scad file but I can not get the photo to load in it.
I put the photo in the scad directory

here is the scad file.
use <utils/build_plate.scad>
use <write/Write.scad>

// preview[view:south, tilt:top]

/* [Image] */

// Standard is 4:3 aspect ratio, HD is 16:9
picture_shape = "standard"; // [square:Square, standard:Standard Photo, hd:HD Wide]

picture_orientation = "horizontal"; // [horizontal, vertical]

// Chose small for a quick, less detailed print
pane_size = "large"; // [large, small]

// Simple photos with many shades of light/dark areas work best. Don't forget to click the Invert Colors checkbox!
image_file = "image-surface.dat"; // [image_surface:100x100]

/* [Adjustments] */

include_hole = "yes"; // [yes, no]
hole_diameter = 10;

// What layer height will you slice this at?  The thinner the better.
layer_height = 0.2;

// The lower the layer height, the more layers you can use.
number_of_layers = 12; // [8:20]

/* [Text] */

text_line_1 = "";
text_line_2 = "";
text_line_3 = "";
text_line_4 = "";
text_line_5 = "";

text_size = 10;
text_vertical_position = 0; // [-80:80]

// In case you like viewing the lithopane from the other side
text_reverse = "no"; // [no, yes]

/* [Hidden] */

// base (white) will always be 2 layers thick
min_layer_height = layer_height*2;
hole_radius = hole_diameter/2;
height = layer_height*number_of_layers;

//for display only, doesn't contribute to final object
build_plate_selector = 0; //[0:Replicator 2, 1:Replicator, 2:Thingomatic, 3:Manual]

//when Build Plate Selector is set to "manual" this controls the build plate x dimension

//when Build Plate Selector is set to "manual" this controls the build plate y dimension
