Can't say it works. At least for me it doesn't. I tried it on Firefox, Chrome and Vivaldi without much success. I just get the default clumsy vndb interface when I search by title/tag. If there's something to be done at the user's end, the add-on doesn't do a very good job of explaining it. I expected it to "automatically add images to entries" as mentioned in the description but that's clearly not happening, period.
