Image uploads not working

Whenever I use any image to upload, I get this. It doesn't show up in the body of the text. Is there a certain number of posts before I get this feature or is there something faulty at my end? I tried Chrome, Firefox and Edge but still face the same issue.




I eventually have to paste the link of the image.

Update...

Alright just realized that Imgur is blacklisted here. Postimg works fine.
