clear all();
close all;
img = imread('E:\Matlab Methods\Thesis Code\example.jpg');
imgdata = imresize(img,0.5);

This is not an error. It is just a warning that your image is larger than your screen size. If you don't want to see this warning, just use:

imshow(I,'InitialMagnification','fit');

This will fit the image to your screen size.

Regarding the "values are not shown":

if I am not wrong, the pixel values are there, but not visible in the image?

In this case, try using a different display range.

Like

Full display range: [] = [low, high] = [min(I(:)) max(I(:))]

imshow(I,[],'InitialMagnification','fit');

or choose a different [low, high] based on your requirement

It seems correctly, the first line should be clear all;

1. You should verify that the image is existing;

2. Is the img variable valid? I mean that is the img empty or not?

3. the image example.jpg can be opened by your local desktop app, such as windows painter or others app that can view an image
