Removing content from a site and from search are different tasks
A search engine displays a result found on another website. Changing that result does not mean the original material has ceased to exist. This distinction is the starting point for work on unwanted publications and images.
Collect precise addresses
You need the page URL, the image URL and the addresses of relevant copies. Record when the material was found and its context. A screenshot helps document the issue but does not replace a direct link.
Check the grounds
Copyright infringement, a factual error and the disclosure of certain personal information involve different grounds and procedures. A copyright complaint is not appropriate simply because a publication is unwelcome.
Verify the outcome
After the original source changes, search results may need time to update. Google provides processes for refreshing outdated results. Each service has its own rules and makes its own decision.
Official guidance: removing images from Google Search.
