Hello all

Not much discussions on this list nowdays, so I thought of sharing one of
the questions which I came across recently in college CTF, and was unable
to solve it.

The question is the image below :

https://docs.google.com/file/d/0B4G8EjUmqNchUlg1cGI3UFl4SEE/edit?usp=sharing

(Image is white, with some grids)

I have to decrypt some information out of it. I am not able to think from
where to start. I am *not* good at Image processing. Please give me some
suggestions on how to start ?
