While a website's content is the largest factor in the content, it is important to also have well-designed images. Images on websites are frequently viewed before any text and can often be the deciding factor on whether or not a person will stay on that page.
Images are easier to process and remember than words so it is important to give your audience something worth remembering. Images are an opportunity to create a better experience for your website visitors, give them more information about your products and services, and ultimately help them trust you.
Images play an integral role in making sure that people don't just glance at your site for 10 seconds before moving on to something else - they help people understand what you're trying to say by telling a story with a single image.
