  • I don't even see an edit box control referred to in your code. Anyway, your code will just overwrite all the images in the display and the only one you'll most likely even see is the very last one. By the way you need to be using fullfile() with (the very badly-named) "a", or else it won't find your images
    currentfilename = imagefiles(ii).name;
    fullFileName = fullfile(a, currentfilename);
    currentimage = imread(fullFileName);
