Set path or Add path in MATLAB

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);

More details can be found by: doc uigetfile

One way is to give the full path of the image. Hope this helps.

what do you mean by full path of an image?
