I am unconvinced that a photo of this nature adds anything to the article, or will remain that newsworthy. The incident is tragic, and documenting it is important, but a graphic picture of a severed head? Why?
Well, the same could be said of many pictures. We could say "he was beheaded", or we could illustrate it, or we could do both. I see it as fairly similar to the Abu Ghraib pictures, where technically speaking we could convey the same information with words (we could describe what exactly is going on in the pictures instead of showing them), but that serves as a somewhat euphemistic substitute for showing the actual images. I do think it's okay to do that with the severed head though, but still include a link to the image.
This isn't the only image of a dead person on Wikipedia, for what it's worth. There's a fairly close-up and easily-identifiable photograph of John F. Kennedy's corpse on that page, and a photograph on Abu Ghraib of a prisoners' corpse packed in ice, with a face only slightly obscured by a bandage.
