John McAfee--anti-virus pioneer, "person of interest" in Belize murder investigation, and launcher of increasingly bizarre media stories--has been captured. It happened after journalists from Vice accidentally published an iPhone photo of McAfee with embedded GPS data.

In case you didn't know, a lot of newer devices store that kind of information, known as EXIF data, in images. EXIF data is helpful in providing details about a photograph's provenance.

EXIF data revealed the camera's model and settings, plus the editing software used on the image. Cool stuff to know about one of the most iconic photographs of the decade.
