@grfdcx if you're uploading a file from disk with a twitter filename make sure to use ascii2d first to see if you can find the original source, and upload that instead of the file. If you really can't find the source anywhere, use the direct link, like https://pbs.twimg.com/media/FAiNCz2VEAEb4yS.jpg, because that way danbooru will automatically get the full version of the image, rather than an image sample.
