19 I am not persuaded that this probative value was overridden by any prejudicial value attaching to the photographs (as to which see, for example, R v Murdoch (1987) 37 A Crim R 118 at 126 - 127 and R v Telford (1996) A Crim R 427). There is no doubt that they are graphic and distressing. They show the full extent of the complainant's burns at a time when they had been freshly made. However they are, in my opinion, no more distressing than might have been anticipated. Where photographs are of material assistance to a jury in determining an important question or important questions left for their decision it will ordinarily be difficult for a defendant successfully to contend that the jury should not be allowed to see them merely because of their graphic or distressing nature. It will be most unlikely, in such a case, that their prejudicial content would be sufficient to outweigh their probative value. This was, in my opinion, such a case. The photographs were, as I have said, of material assistance to the jury in deciding what had caused the burns and that question was, in turn, central to the innocence or guilt of the appellant.
