I am very confused. As of October 19th, Google brought back a much needed image search feature report offensive images. When you spot an image that is offensive, either pornographic, violently graphic or other - you can use this feature to communicate the offensive image to Google. Now, it is gone again!
Google added this feature in June 2008 after image search became a target for porn and spam. Then when the new image search came in July 2010, Google left out the feature. They brought it back last month and now, it seems to be gone again.
In the past two days, I have seen a dozen threads with very upset searchers wanting to report images from extreme pornographic content to extremely disturbing and violent images. Now the only way to do it is to go through an annoying and confusing process. Instead of a click, click and click.
I do not know why Google removed it and I hope it was just an oversight.
Now, to remove or report images you need to use the URL removal tool, and you will need to know the exact URL of the image you want removed. Here's how to find it:
1. Click the image that you locate in the image search results. 2. Right-click See full size image or Full size, and copy the link address. 3. Paste the URL into a file or document, so it’s available when you use the URL removal tool.
