By using Google's Content Removal page, I could put in a request for removal, for example if a page is no longer online, changed or now gone, and submit it by entering a word that no longer appears in the online page.
My question is: how could I submit a photo to be removed that is no longer available on the online page?
I could still reverse image search a photo and it is still shown in Google search results.
Clarification: I'm trying to remove cached page results of some websites using reverse image search. I have the now deleted (offline) url of the old picture from these sites. I don't know how to use the Google Content Removal tool because usually for these cache removals you type in a word that is no longer on the online page, but in my scenario it's a photo I'm trying to convey is no longer on the page. So what should I type in when Google asks me to enter a word that's not on the online page?
