Remember to always change :large to :orig so you can get the full picture, this should be added to the upload guide or warn you when you are using the wrong url, e.g. same picture but 1920*1080 https://pbs.twimg.com/media/CPe5VRBU8AEigFT.png:orig

If you try to upload a "large" URL via the source field, it automatically corrects it to "orig". I think the only way a "large" upload can happen is if the "large" file is saved to computer and then uploaded from there.
