I'm facing problem with managing directory in MATLAB. I'm working on CBIR, in this project I'm using uigetfile to get image files, these images must be stored in a folder from where i retrieve images and also must add this folder to directory/path, If that folder is not added to path and if i run program i get an error stating 'image.ext' does not exist'.

suppose if user want to search for similar images for his/her own query image and if he/she is not familiar with MATLAB they simply input query image from remote folder which was not added to folder. Then definitely he/she will get error.

Is there any way to get off from this?

loadMNISTimages is not a MATLAB function.

One implementation of it is at https://github.com/davidstutz/matlab-mnist-two-layer-perceptron/blob/master/loadMNISTImages.m

Do not add folders to the PATH only to read some data files. Using the full path is much safer and quicker:

cd('C:\YourDefault\ImagePath');
[FileName, PathName] = uigetfile(*.jpg', 'Select an image file:');
if ~ischar(FileName)
  disp('User pressed Cancel');
  return;  % Or what ever is applicable
end
File = fullfile(PathName, FileName);
img  = imread(File);
