HI,
Before reading the image (imread), you shoud change directory, where the files are present, as like as below
clc;
close all;
clear;
OutputFolder = 'D:\Datasets\handwritten-signatures\sample_Signature\edited'; % Set as needed [EDITED]
dinfo = dir('D:\Datasets\handwritten-signatures\sample_Signature\genuine\*.png');% image extension
for K = 1 : length(dinfo)
thisimage = dinfo(K).name;
cd 'D:\Datasets\handwritten-signatures\sample_Signature\genuine\'
Img = imread(thisimage);
cd ..
Y = imshow(Img);
Gray = rgb2gray(Img);
i = imresize(Img, [227, 227], 'bilinear');
imwrite(i, fullfile(OutputFolder, thisimage)); % [EDITED]
end

You shouldn't be using cd in your functions. imread will accept a full path without requiring the current folder to be changed. Also, why are you using clc,close all,clear? Most of the times that is cargo cult programming. (and you should use the layout tools to make your code more readable)

This is how you can provide the full path to imread:
for K = 1 : length(dinfo)
thisimage = dinfo(K).name;
Img = imread(fullfile(dinfo(K).folder,thisimage));
Y = imshow(Img);
Gray = rgb2gray(Img);
i = imresize(Img, [227, 227], 'bilinear');
imwrite(i, fullfile(OutputFolder, thisimage));
end
