you have to be careful using any images you find online. Sometimes media has been picked up and shared to the point that when we find it we don't know whether it is safe to use or not.

When using images on your site you can get free images from morguefile and others. However, make sure that the license includes the freedom to use on a commercial site. If you use it and the owner finds it without the proper license then you may find yourself liable for paying out a huge sum.

Better to leave Google images alone. If you can, create your own images. If you can't then it is better to shop for those that will be legal to use. You can do a Google search to find lots of places that have them.

I like both Namecheap and Namesilo. They are both good. Namesilo is the cheapest and it is private (for free) for as long as you keep it there.
