you can only make the image show up in the text of pictures you post if you have a premium membership. You can do it in your deviant ID and polls my pasting thumbnails even if you don't have a premium membership and you can do it in journal entries by licking "add media" and then "deviantART" you can also do this in comments if you have a premium membership. (this isn't some add for premium membership or anything, I use plzs so I don't really need one) hope this helps.
Kawaii! Kawaii! All hail twiluna! Now do a Discord Nightmare!
Hmm... I will take this into consideration the next time I am bored.
All aboard! toot toot!
