I saw a prog on UK Horizons this morning called "killer instact" (presented by some loony Australian) - infact there were 3 shows - one about lions, one about big lizards and one about.....sharks.
Interesting they showed footage of great whites coming out of the waters surface - apparently the great white is the only shark that does this. They then went on to show footage of great whites jumping up at big chunks of meat that they were hanging on a large rod over a boat edge.
So, regardless of the legitimacy of the image, great whites do infact go for food in the way depicted in that image (based on what i saw this morning - i know sod all about it !).
Cheers,
