How to have an image in background of plot in matlab

I have a plot from a network of lines in 3D space and I have one image from the object as well. Now I want to put the image file in the background of my plot as a fixed background and then the network should be plotted on that background. By the way, since the Network is in 3D space I can rotate it easily and it is important for me rotate the network on the my combined plot as well.

this is my code that I have written but it shows my plot separately! if I put imshow inside the figure then image will be ploted on the top of my network and I can see only one point of my network. Here is the link of Network and the background image from background Here is my code: the first line plot the image and the rest of the code plot my network of lines:

Img1 = imshow('STP1.png');
figure('name','Distance');
hold on;
labels = cellstr( num2str([1:SIFT_Length]') );  
text(SIFT_3D(:,1), SIFT_3D(:,2),SIFT_3D(:,3),labels,'FontWeight','bold','FontSize', 12,...
 'VerticalAlignment','bottom','HorizontalAlignment','right')
title('Distances Network with colorized lines based on Uncertainty','FontWeight','bold');
hold on
for k = 1:Num_Line_SIFTS
       plot3([SIFT_3D(Line_among_2_Sifts(k,1),1),SIFT_3D(Line_among_2_Sifts(k,2),1)],...
       [SIFT_3D(Line_among_2_Sifts(k,1),2),SIFT_3D(Line_among_2_Sifts(k,2),2)],...
       [SIFT_3D(Line_among_2_Sifts(k,1),3),SIFT_3D(Line_among_2_Sifts(k,2),3)],...
       'o-','Color',[RGB_0_1(k,1) RGB_0_1(k,2) RGB_0_1(k,3)],'MarkerFaceColor',[RGB_0_1(k,1) RGB_0_1(k,2) RGB_0_1(k,3)],'MarkerEdgeColor',...
       'k', 'LineWidth',2)
 end
hold off;

Please help me how can I solve this issue.

I'm not sure I understood your need, nevertheless ...

figure('name','Distance','unit','normalized');

a=axes('position',[0 0 1 1])
%
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% UPDATED CODE STARTS HERE
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%
% Disable zoom
h=zoom;
setAllowAxesZoom(h,a,false);
% Disable rotation
h = rotate3d;
setAllowAxesRotate(h,a,false) 
%
%%%%%%%%%%%%%%%%%%%%%%%%%%
% UPDATED CODE ENDS HERE
%%%%%%%%%%%%%%%%%%%%%%%%%%
%
hold on
imshow('Jupiter_New_Horizons.jpg','parent',a)

t=0:.01:2*pi;
z=sin(t).*cos(t)
a1=axes('position',[0.3 0.3 .5 .5])

plot3(cos(t),sin(t),z,'r','linewidth',3)
grid on
set(gca,'color','none')

This script generates the following graph:

Hope this helps.

What about this:

clear
clc
close all


%// Read image
Im=flipud(imread('STP1_low.png'));

%// Dummy surface to plot.
Z = peaks(25);

%// Prepare image position
shift = 20;
xIm=zeros(size(Z))-shift;

hold on
surface(xIm,Im,'FaceColor','texturemap','EdgeColor','none','CDataMapping','direct')
surface(Z,'FaceAlpha',0.8,'LineStyle','none','FaceColor','interp');
axis on
view(-35,45)

box on
rotate3d on

Output:

enter image description here

You can rotate it and the image stays as the background.
