How to make mobile-friendly images using CSS

How your images appear on mobile devices such as Androids and iphones is very important these days. On April 21, 2015 Google released a new updated algorithm that affects mobile searches in all languages worldwide and has a significant impact on Google Search results. If the images on your website are not mobile-friendly then you will lose rank on Google Search results. This means that if your images bleed through or expand the width of your webpage and your visitors need to scroll to the side you will be affected by the algorithm change.
