for google img search
just setting the url to "https://www.google.com/searchbyimage"
and insert a variable "sbisrc=1" (or2nd safe=off)
everything goes on :p

I found this for Google Lens

Just replace in settings:
http://www.google.com/searchbyimage to
https://lens.google.com/uploadbyurl and
image_url=::$URL:: to
url=::$URL::

No longer works on google, great otherwise and i hope they fix it

Everything else works except for Google image search, which is arguably one of the more useful ones.

No longer working on Google

makes reverse image searching very convenient
best used for artworks as most of the services on it are art-related

Yandex reverse search seems to result in an error when searching materials from tumblr now. They work perfectly if I upload it manually, but not when I supply a tumblr link.

Try this tumblr link for troubleshooting purposes: https://64.media.tumblr.com/b034de2ecd5003fc3113fabb23c15668/9b3c7b7f4d187fce-90/s500x750/b0fa687ddba92830cde4dddd2b10f1c57c689979.gif

Must have for any art lover

does not work. just redirects to the url of the searched image
