• Pay attention to license requirements: If an image is included under an open license, the terms and conditions apply (e.g. attribution, license linking, reference to modifications).

When we use media with a Creative Commons license, we follow the TASL rule for correct attribution.

• Title: State the title of the work, if stated.
• Author: State the author's name and, if available, a link to the profile page.
• Source: Provide link to original source.
• License: State the license name including a link to the license (e.g. CC BY 4.0) and indicate whether changes have been made.

We can technically adapt images to ensure uniform presentation on the web. These measures serve exclusively for readability and loading performance, without distorting the content.

• Crop, scale, and deliver responsively in various resolutions
• Color and brightness adjustments, moderate sharpening, noise reduction
• Compression and conversion into web formats (e.g. WebP, AVIF), embedding alternative texts
• No misleading retouches, no manipulative changes to the content

If people are recognizably depicted, we ensure that the necessary consents are obtained and – depending on the source – that appropriate model or property releases are provided. This applies to your own recordings as well as to licensed material.

• Own recordings: Documented consent of the people depicted; Options for revocation are respected.
• Stock material: Use preferably with model/property release, if necessary; Compliance with the respective license requirements.
• Symbolic photos: Serve for illustration; no conclusions can be drawn about individual patient data or specific treatment results.

We strive to provide meaningful alternative texts (alt texts) for relevant images to make content accessible to screen readers. Decorative graphics can be marked with empty alt attributes to make navigation easier.

• Alt texts describe the purpose and content of the image, not just file names.
• Diagrams/Infographics: Core information is also presented in continuous text or in list form.
• Contrast and readability: When combining text and images, we pay attention to sufficient contrast and scalable display.

If you have any copyright questions or indications of possible legal infringement, please inform us. We will examine your concern immediately and, if the complaint is justified, we will correct or remove it.

• Contact by email: info@citak.de
• Please provide the affected URL, a description of the medium and – if available – proof of your rights.
• We will confirm receipt and get back to you with an assessment and next steps.

These image credits are continually maintained. Since individual media are marked directly on the image for practical or licensing reasons, there may be discrepancies between the embedding and this overview in individual cases. The information provided on the medium is always decisive.
