Where I live I saw an ad, it only says "canyousolve.it" wich is a page with some kind of puzzle. I noticed the image in there it's called "more-than-an-image" so I can only imagine it has a hidden message. I don't know if it's related to steganography, but I think it leads to another page. If you look at the image, near the upper-left corner there is a horizontal red bar and if you play with hue, luminosity and other things, it appears to say "www" and something else that isn't readable. I don't know if I'm going through the right path.
Any ideas?
Here's the image:
