Posting Images on the Downs

[Imladris]

I have a question that might be considered stupid, but it's been bugging me for quite some time.

When the Barrow-wight says this:

If the image resides on someone else's space

Does that include images found on a Google search? I ask this because I'm not sure if Google could be termed as "someone else's space" or a true site because it's a search engine right?

So forgive this question if this is stupid.

Cheers!
