Just add various pixels of flower's image into car's image to be one image. This part should be same size and pasted at top and bottom of car's image

Try this. It will add the smaller image to the lower right part of the larger image.
% Initialization steps.
clc; % Clear the command window.
close all; % Close all figures (except those of imtool.)
clear; % Erase all existing variables. Or clearvars if you want.
workspace; % Make sure the workspace panel is showing.
format long g;
format compact;
fontSize = 20;
rgbImage1 = imread('car.jpeg');
subplot(2, 2, 1);
[rows1, columns1, numberOfColorChannels1] = size(rgbImage1)
title('Image 1', 'FontSize', fontSize);
rgbImage2 = imread('pink flower.jpeg');
subplot(2, 2, 2);
[rows2, columns2, numberOfColorChannels2] = size(rgbImage2)
title('Image 2', 'FontSize', fontSize);
% Find out where the smaller flower image needs to be so that
% it will be in the lower right corner of the larger car image.
row3 = abs(rows1 - rows2) + 1
column3 = abs(columns1 - columns2) + 1
% Add them
sumImage = rgbImage1; % Initialize
subplot(2, 2, 3:4);
v = (double(rgbImage1(row3:end, column3:end, :)) + double(rgbImage2)) / 2;
sumImage(row3:end, column3:end, :) = uint8((double(rgbImage1(row3:end, column3:end, :)) + double(rgbImage2)) / 2);
subplot(2, 2, 3:4);
title('Image 1 + Image 2', 'FontSize', fontSize);
