Copyright and images on your website

Licenses

Licenses determine how images can be used on a website. There are different types of licenses that you should know about:

1. Royalty-Free (RF) – This license allows broad use of an image for a one-time fee. This does not mean the image is free, but that you can use it multiple times without incurring additional costs. However, royalty-free images often have limitations regarding the type and scope of use.
2. Rights-Managed (RM) – This license offers more specific usage rights defined by parameters such as duration, location, or method of use. This type of license is more restrictive but allows for more tailored usage to the needs of the user.
3. Creative Commons (CC) – These licenses allow free use of images, often with certain restrictions. For example, some CC licenses require attribution to the author or prohibit commercial use.

Where to source images for your website?

1. Stock photo agencies – Websites like Shutterstock, iStock, or Adobe Stock offer a wide range of images under royalty-free and rights-managed licenses.
2. Free stock photo websites – Portals such as Unsplash, Pexels, or Pixabay offer images usually under the Creative Commons Zero (CC0) license, meaning the author has waived their copyright.
3. Specialized collections – Museums, libraries, or universities often provide images that are in the public domain or under Creative Commons licenses.

GDPR and personal images

1. Protection of personal data – The General Data Protection Regulation (GDPR) introduces requirements regarding the privacy of individuals whose images are published. You must obtain explicit consent from recognizable individuals, especially in a commercial context.
2. Consent for image use – Consent should be written and include a detailed description of how the image will be used. This is particularly important when images are used for marketing or advertising purposes.
3. Anonymization – In cases where obtaining consent is not possible, consider anonymizing individuals in the images, for example by blurring faces.

Choosing images for your website

Selecting the right images for your website is crucial for the success of any online presence. Proper images can not only capture users’ attention but also effectively communicate your company’s values and offerings. Below are important aspects to consider when choosing images:

Target audience

• Understanding your audience – It is essential to know your target group: their age, interests, needs, and expectations. The images should be chosen to resonate with the aesthetic preferences of your audience.
• Visual personalization – When selecting images, consider whether they address the questions and solve the problems of your specific target group. For example, younger audiences may respond better to modern, innovative visuals, while older users may prefer more traditional and subdued images.
• Testing and feedback – Regular A/B testing and gathering user feedback can help determine which images work best and engage your target group effectively.

Site aesthetics

• Visual consistency – Images should blend seamlessly with your site’s overall design, including its color scheme, typography, and layout. This consistency helps build a professional and easily recognizable brand image.
• Image quality – High-quality images are essential. They should be sharp, well-lit, and produced in high resolution.
• Style – The images should reflect the style and tone of your brand’s communication. For example, dynamic, colorful images may be ideal for a youthful fashion brand, while more subdued and elegant photos might work better in the corporate or financial sectors.
• Uniqueness – Images should be distinctive and stand out from the competition. Using unique photos or custom graphic designs will help maintain a unique brand image.

Image optimization for your website

Image compression without quality loss

• Choosing the right format – JPEG is ideal for images with a lot of colors, PNG works well for images with transparent elements, and SVG is excellent for vector graphics. Formats like WebP offer compression while maintaining quality.
• Compression tools – There are many online tools that allow for effective image compression without visible quality loss.
• Optimizing dimensions – Before uploading to the server, images should be resized to the maximum dimensions they will be displayed at. There is no need to use images with a higher resolution than required.

Alternative text and tags

• Alternative text – This is a short description of the image content that is read by screen readers for people with disabilities and is displayed when the image cannot be loaded. It should accurately describe the image, allowing its context to be understood without seeing it.
• Title tags – These can be used to add additional information about the image, which is displayed as a tooltip when hovering over the image.
• Use of keywords – Using relevant keywords in the alternative text and file names can contribute to improving your site’s SEO.
