This is a rather simple userscript that uses the pixiv thumbnail to check if the image exists on Danbooru, and if exists..adds a dotted border to the thumbnail.
This script basically:
Grabs pixiv thumbnail url.
Converts to original image url.
Uses the danbooru API to check the source (via post/index.json?tags=source:)
If image exists, add dotted border to thumbnail.
Made this simply due to occasionally finding a rather awesome image on pixiv > tagging & uploading to danbooru, just to find out it had already been uploaded (Therefore making half the tagging done a waste of time).
Known Issues:
- Does not work with manga posts.
