Mysterious - recently I've been getting about 20 spams a day of the "hello, I am tired today" format, with an attached image whose filename is just "me" (not even a file format extension). The files are gifs. They are all the same picture, but they are not all the same image. The cropping varies, and there is noise in the image which also varies. Is there perhaps some sort of steganographic message concealed? A couple of images to show what I mean; one and two. I recommend loading them one after the other in the same window, so you can click 'back' and 'forward' to see the difference.
The other possibility, of course, is that they just have added noise and cropping to make it so spam-filters can't just identify and reject the specific file.
