It is very important that you don't just search the web for images and use whatever you find. This is copyright infringement and can get you in big trouble legally. Not only will you need to stop using the images but you may also be required to pay restitution to the legal copyright holder for using their images without permission. You can save yourself a lot of hassle from the start by using images that you are allowed to use.
