@Boznsj You need to be tagging the artist properly on upload. And tagging more in general. Further, gelbooru is not a proper source.
In this case, the artist's twitter handle is right in the image, so it took me like 30 seconds to find the proper source. There are like 50 other images of this character that are really high quality from the same artist. If you want easy stuff to upload it's right there.
