imread() the color image, rgb2gray() it, imresize() it to 256 x 256 or imresize() it to 256 on the shorter side and imcrop() the rest of the longer side away if the image is not originally square.

Lena is available here: http://www.cs.cmu.edu/~chuck/lennapg/ or here: http://www.lenna.org/full/len_full.html. Note: the second link is the full image which contains nudity. Playboy has given permission to use the cropped version in research.
Peppers is a standard demo image that ships with the Image Processing Toolbox. You can get a gray scale version like this
rgbImage = imread('peppers.png');
grayImage = rgb2gray(rgbImage);
imwrite(grayImage, 'grayPeppers.png');
To get the mandrill baboon demo image in gray scale, do this:
storedStructure = load('mandrill.mat')
rgbImage = ind2rgb(storedStructure.X, storedStructure.map);
grayImage = rgb2gray(rgbImage);
imshow(grayImage);
imwrite(grayImage, 'grayMandrill.png');
