I always have a hard time interpreting Twitter posts. Did you link to two images in this post? Were they things you observed when trying to upload an avatar with a filename in accordance with this bug? Why does Twitter crop the images? (This it what I see: https://u.pomf.is/dmomwl.png )
Yes, there are two images. You should be able to click on them separately to open the full images [0][1]. The first screenshot shows a preview of the file with its name which I tried to upload to Twitter, the other one shows what I observed locally through htop when running `convert` on that filename.
