This is not a panty shot, as Miss Mrtian does not wear panties. In fact Miss Martian, like Martian Manhunter, does not wear clothes at all. Her 'costume' is just the outer layer of her skin shapshifted. Therefore, while this isn't a panty shot, it IS a nude shot.

Just like every other panel J'onn or M'gann have ever been in.

Now go back through your JLA and Teen Titans collection with that in mind.
