Unfortunately Dronestagram (still) shows all photos reduced and cropped to 1200 x 674 or 1200 x 800.
It's useless for panoramas and you can't see photos full screen.
Skypixel isn't much better but it does show a reduced version of the full image.
Unfortunately SKY pixel has been semi-non-functioning for quite a while.
DJI say they are going to fix it - but they've been saying that for a while now.
To be able to display your images better, 500px is a better option.
It's not restricted to aerial work but a lot of drone photographers use it.
Like this guy: Meta4
Search there for Drone or DJI and you'll see a lot of good work
