Specify the 'MultiSelect' option to be 'on':
[baseFileName, folder] = uigetfile(...,'MultiSelect', 'on')

You can get all the image files present folder using dir . Check the code below.
Files=[dir('*.jpg');dir('*.png');dir('*.bmp')] ; % Get jpg, png and bmp files in the present folder
N = length(Files) ; % Total number of image files
for i = 1:N % loop for each file
I = imread(Files(i).name) ; % Read the file
% Do what you want
end

sorry for my wrong question, I want to open multiple image files with GUI not intend to read. [fileName,pathName] = uigetfile('*.*','Select Images')
imageDir = fullfile(pathName, fileName);
images = imageDatastore(imageDir)
This code is ok for 1 time to select the image. But I want to select N times.

[filename, pathname] = ...
uigetfile({'*.jpg';'*.png';'*.bmp'},'File Selector');
