Those images are clearly CG but the WZ-8 can be carried under the H-6... just not this variant of the H-6 shown in the images. Perhaps only capable of being currently carried and launched by H-6.
It's also a high altitude drone so the CG is a poor representation of how WZ-8 is used. Just lazy creator I suppose.
The WZ-8 is launched from a H-6K/N/G platform and dropped at altitude and the drone then climbs. It isn't some low altitude attack drone to be dropped just above treetops.
