You can define the path of a file to access it:
Folder = 'C:\Temp\';
FileList = dir(fullfile(Folder, '*.jpg'));
for iFile = 1:numel(FileList)
File = fullfile(FileList(iFile).folder, FileList(iFile).name);
% Do what you want with this file, e.g.:
Img = imread(File)
end

help cd

cd is slow (searches for MATLAB files), changes function scope, and makes debugging harder.
Much better: access data files using fullfile and absolute/relative filenames.

It is unsafe to change to a specific directory only to access the included files. Using absolute path names is better, because this is not confused by GUI or TIMER callbacks, which call cd again unexpectedly.
