How much do film crime victims make?

I was just watching an early episode of DCI Banks. Viewers see a photo of the murder victim, but the person in the photo never has any lines or other scenes. They're just a body in the morgue, sometimes visible during the postmortem, but that's all.

I assume there is scale pay for this kind of thing, correct? Are there 'professional' victims in the industry? I imagine they don't make much - just a random thought I had...
