I have a folder that contains 16 images. From these images, 9 of them have a dimension of 1280x1024, and the rest of them have different dimensions. How can I read and display these 9 images only?

folder = 'C:\Users\Documents\PhD\Analysis\Hot-Spot\'; 
jpeg_files = dir(fullfile(folder,'*.jpg'));
nfiles2 = length(jpeg_files);
for k = 1:nfiles2
    currentimage{k} = imread(fullfile(folder,jpeg_files(k).name));
    figure; imshow(currentimage{k});   % creates a new window for each image
     
end

Try this

folder = 'C:\Users\Documents\PhD\Analysis\Hot-Spot\'; 
jpeg_files = dir(fullfile(folder,'*.jpg'));
img_info = cellfun(@(x) {imfinfo(x)}, fullfile({jpeg_files.folder}, {jpeg_files.name}));
img_dim = cellfun(@(x) {[x.Width x.Height]}, img_info)';
img_dim = cell2mat(img_dim);
idx = all(img_dim == [1280 1024], 2);
jpeg_files(~idx) = [];
nfiles2 = length(jpeg_files);
for k = 1:nfiles2
    currentimage{k} = imread(fullfile(folder,jpeg_files(k).name));
    figure; imshow(currentimage{k});   % creates a new window for each image
     
end
