The legal 'right to be forgotten' has been around since 2014 but recently Google have extended this. Now, any person under the age of 18 (or their parents/guardians) can fill in a form and request that one or more images are removed from Google search results.
This is good news, there will be many reasons why a young person might want an image to be removed from Google search results, e.g. embarrassing photos from when they were younger, perhaps uploaded by a parent. The removal is from search results within the UK, not the rest of the world. For example, if someone has their image removed and someone tries to search on google.co.uk, they won't be able to find it. But if someone searches on google.com, the image will still be there.
