Images play a key role in the look of your website. From adding extra interest to the site, to showing people more clearly what your site is all about, images make it easy for readers to understand the purpose of your site.
There are lots of ways to get images for your site. Firstly you could spend a little money and have some professional photos taken for your site. This is useful when you have products or items to show off, as you can display them nicely. Another way to get images is to use royalty free stock images (available from different websites).
