MATLAB: For- loop to plot multiple images on a figure

for loopMATLAB

Hello,
I have 6 images that I want to insert on the one plot at the same time based on the latitude and longitude that specified in a table (namely coordinate). All 6 pictures name like this: filename1.png, filename2.png, filename3.png, … filename6.png; Which should plot using the information in the coordinate table first, second, third …, and sixth respectively.
I know how to plot one by one them using this code:
% This code for plot just first image
LowerLeftCornerLon = coordinates.LowerLeftCornerLon(1); % the first image uses the first row of the table, second must use second and so on
UperrRightCornerLon = coordinates.UperrRightCornerLon(1);
LowerLeftCornerLat = coordinates.LowerLeftCornerLat(1);
UperrRightCornerLat = coordinates.UperrRightCornerLat(1);
img1_lon = [LowerLeftCornerLon,UperrRightCornerLon];
img1_lat = [LowerLeftCornerLat,UperrRightCornerLat];
[c, ~, tr] = imread('img1.png');
im = image (img1_lon,img1_lat,flipud(c));
im.AlphaData = tr;
% then use hold on and do the same thing for the second picture but this time reading the second row of coordinate table
But I have some problems with writing a loop in order to plot all of them automatically.
Here is my try:
hold on % plot pictures on the previous plot
% first read all images from dir
if true
   srcFiles = dir('F:\university\matlab\mypictures\*.png'); 
   for i = 1 : length(srcFiles)
       filename = strcat('F:\university\matlab\mypictures\',srcFiles(i).name);
       IMAGES{i} = (filename);
  end
end
for i=1:numel(IMAGES)
    img_lowlat(i) = coordinates.LowerLeftCornerLat(i);
    img_lowlon(i) = coordinates.LowerLeftCornerLon(i);
    img_uplat(i) = coordinates.UperrRightCornerLat(i);
    img_uplon(i) = coordinates.UperrRightCornerLon(i);
    
    img_lon(i) = [img_lowlon(i),img_uplon(i)];
    img_lat(i) = [img_lowlat(i),img_uplat(i)];
    
    hold on
    [c, ~, tr] = imread('IMAGES{i}');
    im = image (img1_lon,img1_lat,flipud(c));
    im.AlphaData = tr;
end
But this not accomplished well and after that, I get this error:
Unable to perform assignment because the indices on the left side are not
compatible with the size of the right side.
Did you know how can I do to fix my for loop and plot all images on the same plot successfully?
Really thank you

The original error was concerned with
img_lon(i) = [img_lowlon(i),img_uplon(i)];
img_lat(i) = [img_lowlat(i),img_uplat(i)];
where a two-element array (right-hand side) was being assigned to a scalar on the left-hand side. This was replaced with
img_lon = [img_lowlon(i),img_uplon(i)];
img_lat = [img_lowlat(i),img_uplat(i)];
hold on
[c, ~, tr] = imread(IMAGES{i});
im = image (img_lon,img_lat,flipud(c));
