MATLAB: The directory of simulation

diruigetdir

I am using this code to get all images in a folder by user:
d = uigetdir(pwd, D);
imagefiles = dir(fullfile(d, '*.jpg'));
nfiles = length(imagefiles);
Then in a for loop I will do some calculations on the images:
k = 1:nfiles    
   currentfilename = imagefiles(k).name;
   I = imread(currentfilename);
   .
   .
   .
when running the code I get this error:
Error using imread>get_full_filename (line 568)
File "1.jpg" does not exist.
Error in imread (line 377)
    fullname = get_full_filename(filename);
Error in DemoBoundary29sept2018edit3ReadsImagesfromfolder (line 30)
   I = imread(currentfilename)
But 1.jpg exists in that folder. I think the reason is that the folder that the code is saved is different from folder that the images are.
Any idea how to solve the issue?

   currentfilename = fullfile(d, imagefiles(k).name);
The .name field returned by dir() never includes folder information: it is the basic file name (including extension) only.
Since R2015b or so, there is also a .folder field, so
   currentfilename = fullfile(imagefiles(k).folder, imagefiles(k).name);
could be used. That is useful if you used wildcards in folder specifications.
I find it easier to attach the folder names before-hand:
   filenames = fullfile(d, {imagefiles.name});
and then extract filenames{k} and use that.
