Web browsers offer the option to search for images on a search provider via a context menu on images, sending the said image to them.
This uses the search engine settings to do this, however Kagi doesn't offer any documentation as to how to configure this.
This is the relevant section I'm referring to for a browser called Vivaldi:
Using something like 'https://kagi.com/images?q=%s' will not work, and looking at the other default search engines with settings configured for image searching, they do things by uploading the file to the search engine. This is preferable as when just passing along a url, Kagi may not have access to the url and the image stored there.
Could we see some instructions on how to do this please, or if it isn't currently possible with Kagi's setup, have it made a feature please?
