picture = imread('pict.jpg')
image(picture)
This is the picture that I want to get:

@Omer Al Sumeri, sure. Just start a new thread and attach your indexed image file. There, show us a screenshot of what you're getting when you use my answer from below
[indexedImage, cmap] = imread('Charizard.jpg.png');
imshow(indexedImage, cmap);

It's an indexed image. Get the second output of imread(), which you are not asking for now. It will be the color map. Then apply it with the colornap() function.
