Quoting myself from the other thread as it apparently needs to be said here as well.

It's not that they put them on google images. It's what people tag them for for people legitimately searching for images to use for commercial reasons.
Also, just because it is on google images does not mean that an image is free for you to take and use for what ever you please. There can be legal ramifications behind "stealing" some of these images.
I suggest that if you plan on creating more photoedits, I suggest signing up at places that have free use art (i.e. DiveiantArt, which has stock images for people to use) and go from there.
Trust me, artists do not like having their pictures/art/images stolen for kids to play with. Some artists will pursue it to the furthest extent of the law, and trust me, it is not something you want to be put through.
