@nicole-steinberger Google search brings up any images used on the Internet. Those images are like content on the Internet – not all of it is free for public use. Most of it is copyrighted.
if you buy images from iStockPhoto, you’re buying the license to use it as described in their usage terms.
If you want free images you can use on your blog, you can use Flickr Advanced Search and check the box to search within Creative Commons licensed images. These are images that the owner is granting permission for anyone to use in exchange for attribution.
