You are not allowed to use images on your website found on Google or from random websites!
But you are not a photographer and you do not have professional images! Luckily there are free images on the internet that you can use for your website. We recommend two websites, (links below) that you can get images to use freely on your website. If you would like to thank the people who supplied the images you may tip them online. You may also add a back link to them in order for them to get more exposure.
What if you cant find what you are looking for?
We recommend that you buy images at Can Stock Photo, they are fairly priced and a lot less expensive than their competitors.
