Are you asking to write a code to read any image from the computer any directories/folders without mentioing the path of the directory?

Well, you'll have to tell it somehow; what groundrules are in play for allowable solution space?
Adding a zillion subdirectories and cd 'ing to them is NOT a recommended solution.
Two possiblilities out of many -depending upon the above question:
- If no user intervention, use the OS dir() or similar to do a directory search from some point for the specific files wanted and parse the results to find the base directory. Somewhat problematic if there are many subdirectories and files and can't isolate a starting location very closely, but possible in theory.
- I there is the possiblity of initial human intervention, use the uiopenfile dialog and let the user navigate to the starting position desired.
Other ways would be variations on a them depending upon just what it is that is meant/desired/required to meet the demand.

maybe you can use this:
to add every folder to the path before importing the files

Maybe you should just call uigetdir() and let the user decide the folder so you don't have to write any folder name in advance.
folder = uigetdir()
filePattern = fullfile(folder, '*.png')
% Get all PNG files in the user's selected folder and all subfolders.
imds = imageDatastore(filePattern, 'ReadFcn', @imread)
allFileNames = imds.Files
