In my humble opinion, pictures that do not show characters from My Little Pony would not be particularly enjoyable to the majority of people who browse DB.
However, I wouldn’t mind if you got a permission to post them as long as they are tagged ‘barely pony related’.
There we go, thank you for not letting this devolve into a pissing contest.
And now I shall temporarily refrain from posting such content until official word is out.
I would say no. We’ve been allowing show-style art of random animals, because people are interested in seeing how this or that creature would look in the show.
With things like this, they’re neither actually ponified, or in the show style (as in on model, anatomy and such aside), or are things that would have a reason to be seen in the show.
