Still have to click on "view image" cause I cannot, for the life of me, figure out how to use the bookmarklet without opening the direct image. Or figure out how to use the official one for that matter.
But it working now, baby!
Left click the image on Pixiv so the full size is displayed. Then click the bookmarklet and you'll be brought to the upload page.
If you click the bookmarklet without first opening the full size then it does work and lets you upload, however the image preview on the upload page won't always work if you do this.
