The answer is

Chicago

Following Dan Russell's partial answer:

Taking the 2 least significant bits of each pixel, I get this image: enter image description here

Thanks to @f'' in the comments, the interpretation of this is:

Those are pictures of a clipboard, a bin and Kim Dotcom, forming pastebin.com.
Accessing http://pastebin.com/L0szeSrH we see the question "What city?" and a picture of a track which appears to be located in Chicago, more specifically the UIC-Halsted station.

So there's definitely a dude in there... (What has two thumbs and loves toast? This guy!) But I don't think that's enough, and given the tag I don't think I have the expertise to go further.
