Greasy Fork

It works is I go on google.com > click on "images" (up-right corner) and then search: the url is https://www.google.com/search?hl=it&tbm=isch&q=anyname
It does not work if I go on google.com, search anyname directly and after the research page has come, I click on images: the url is https://www.google.com/search?q=anyname&tbm=isch
So I think need to be integrated also the "/search?q=search-term&tbm=isch"

Yes, I saw that as well.
Use this regex instead: https?:\/\/(www\.)?google\.[^\/]+\/search\?.+tbm=isch.*
This allows for tbm=isch to be the last parameter, if nothing follows.

...uhm sorry, but I don't know how to use a regex in the script.
