well, the dimensions are the same here soooo....¯\_(ツ)_/¯....from now on I'll just look to download the biggest version of the pics.
How are you uploading these? All you need to do is input the source url, unedited, into this. You don't need to download anything. Are you getting these images from somewhere other than the source you're providing?
I right-click & open the image itself from its source into a separate tab, delete what comes after the JPG, enlarge it, download it, and then upload it from my own files, just in this instance, with or without the stuff after the JPG, it's still a mismatch even though this file has the same dimensions as the source.
I keep it in my files for when I want to upload it, plus it'll save me the time to look for the source again as I can just drag & drop the post onto google images which just makes it so much easier to find the original source.

Yeah... Don't do that. It's a mismatch because that whole process messed with the image's integrity. You basically created an entirely separate image. From all supported sources, such as twitter, all you need to do is input the source url, in this case https://twitter.com/old__night/status/1021415817546641409, into the text field at https://danbooru.donmai.us/uploads/new. Danbooru will then grab the exact, unmodified image for you to tag and upload.
