Best Practices for Effective Image Use


Relevance & Context

One of the most important principles for effective image use is relevance. Images must serve a purpose, support the content, and the message of a website. Every image that is placed on a webpage should be intentional while adding value to the message or functionality. Images that are included in websites with little to no purpose or relevance are considered unnecessary and increases visual clutter.

Consistency in Style

Consistency in images across all web pages within a website is important as it helps maintain a predictable and structured visual identity. This includes using images that match tone, color palette, sizing, and positioning. If users are able to predict the layout and structure of a website, it allows them to focus more on the content of a site rather than getting distracted by random image placements. Consistent styles in imagery can also support brand recognition and make the site feel more professional overall.

Quality & Resolution

The quality of images directly influences the audience’s perception of the professionalism and trustworthiness of a website. Low quality images can make a website feel more outdated and less trustworthy. Users will be less likely to use sensitive information to create accounts, purchase products, or even continue navigating the site due to the lack of professionalism. High quality images can immediately improve user perception at first glance making them seem reliable and trustworthy.

Accessibility

Accessible design ensures that all users, including those with disabilities, can utilize and understand a website. In terms of imagery, an important feature can help those with visual impairments understand the context and importance of an image. Every image you include in a web page should contain descriptive alt text that clearly describes what the image’s content and function is. This is helpful to those with visual impairments and rely on screen readers.


Real-World Example: Good Image Usage

The following example above refers to Microsoft’s website. It is a great representation of what good image usage looks like. It effectively uses a hero image on their homepage that grabs the users attention, utilizes icons for improved navigation, professional product photos, and shows how images can be used to improve a site’s page layout. Another thing you can notice with this example is how they use consistent styles in their image. They use the same color palette throughout the website while keeping a minimalistic approach to their images.

The following example refers to the website LingsCars.com. This website is a car dealership page that represents very poor image usage. They use a very distracting background image, include images that serve no purpose, is difficult to navigate, and uses low quality or unprofessional visuals. Along with the abundance of images that serve little to no purpose, they also include too many animated images (GIFs) that make the site even more distracting.
