You might want to take a look at <a href="http://blogs.mathworks.com/steve/2006/10/17/the-story-behind-the-matlab-default-image/" rel="nofollow">this post</a> for a simple way to hide and reveal information in an image.

It would also be helpful to provide a screen shot, if possible, of what the image is supposed to look like.

As an extra-credit problem for my class we have an image which we must find the hidden riddle and answer it. I believe the image has some pixel layers removed, using the command , is there any way to put layers back on top? Thank you, Billy Steve,
