Whatever the problem is, it doesn't originate in the code you've shown. I get no such result
>> img=uint8(randi([0,255],512)); LSBImg =( im2uint8(img) - rem(im2uint8(img), 2)); g= imsubtract(img,LSBImg);
>> whos img LSBImg g
Name Size Bytes Class Attributes
LSBImg 512x512 262144 uint8
g 512x512 262144 uint8
img 512x512 262144 uint8

What code? I didn't see any code - perhaps he edited it away. The code Matt J has look similar to a question I answered in http://www.mathworks.com/matlabcentral/answers/90789#answer_100248 except that I operated on the uint8 image directly and didn't use im2uint8:
% Set LSB = 0
grayImage2 = grayImage - rem(grayImage, 2);

Try this:
% Set LSB = 0
grayImage2 = grayImage - rem(grayImage, 2);
