Regardless of what your site(s) may or may not make - my suggestion is to register your business as either a sole proprietorship or incorporate it. That way if you don't generate enough revenue with the sites themselves, you can at least enjoy a few tax write-offs on the business.
We incorporated a few years ago, and since we do our own photography...we can be quite creative at tax time when we write-off photo props and gear (who's to say what is and isn't a "prop").
Don't expect to be Howard Hughes by this time tomorrow.
