That picture isn't clear, but it looks like the jack stand is under the part of the frame that is angled upward. You never, ever want that. Only under the flat part of the frame. The stand could slide up the frame otherwise.

Personally, I usually put my jack stands under the lower control arm cross shafts or up in the notch in the lower control arms outboard of the coil spring pockets.
