if all the files are in the same folder you could use:

 pathtofiles            = '/path/to/folder/';
 allfiles               = dir(pathtofiles); % use dir to get the file 
                                                   % information of directory
 selection_of_jpg_files = ~([allfiles.isdir])      % only files that are not (~) 
                                                   % a directory
 for index = find(selection_of_jpg_files)
    if strcmp(allfiles(index).name(end-3:end),'jpg') % check if the file is a jpg 

        IMG = imread(fullfile(pathtofile,allfiles(index).name) % load the file
        % now do something with the IMG...

    end
 end
