Stock photos are a valuable resource for bloggers, designers, and businesses. However, using them without proper attribution can lead to copyright infringement, even if the image is free. This guide explains how to attribute stock photos correctly, covering different license types, attribution formats, and common pitfalls. Whether you are using images from free stock photo sites or paid platforms, understanding attribution is essential to stay legally compliant.

Why Attribution Matters

Attribution is a legal requirement for many stock photo licenses, especially Creative Commons (CC) licenses. When a photographer or artist shares their work for free under CC, they rely on attribution to receive credit and to allow others to find their work. Failure to attribute can result in a takedown notice, legal fees, or damages. Even on platforms like Unsplash, which use a very permissive license, attribution is appreciated and often required by the photographer’s terms.

The key principle is: give credit where credit is due. Proper attribution respects the creator’s rights and helps build a culture of sharing. For a deeper dive into licensing, see our article on Creative Commons Licenses Explained.

Types of Licenses That Require Attribution

Not all stock photos require attribution. Here are the most common license types:

  • Creative Commons Attribution (CC BY): You must credit the creator in the manner specified. Commercial use is allowed.
  • Creative Commons Attribution-ShareAlike (CC BY-SA): Same as CC BY, but derivative works must be shared under the same license.
  • Creative Commons Attribution-NoDerivs (CC BY-ND): Credit required; no modifications allowed.
  • Creative Commons Attribution-NonCommercial (CC BY-NC): Credit required; non-commercial use only.
  • Pixabay / Unsplash / Pexels licenses: These are often “no attribution required” but many creators still appreciate credit. However, read the specific terms—some images may have restrictions.
  • Public Domain (CC0): No attribution required, but it’s good practice to credit anyway.

Elements of a Proper Attribution

A complete attribution typically includes four elements (the “TASL” formula):

  • Title: The title of the work (if provided).
  • Author: The creator’s name or username.
  • Source: A link to the original work (URL).
  • License: The license type and a link to the license deed.

Example: “Photo by John Doe on Unsplash” is a minimal attribution. A more complete version: “Photo by John Doe / Unsplash / CC0.” Always check the license for any specific attribution requirements.

How to Attribute on Different Platforms

The format of attribution can vary depending on where you use the image. Below are examples for common scenarios.

On a Website or Blog

Place the attribution near the image, typically as a caption or in a footer. Use a readable font size. Example:

Photo by John Doe on Unsplash

If the license is CC BY 4.0, include the license link:

“Sunset Over Mountains” by John Doe is licensed under CC BY 4.0.

In a Video

Include attribution in the video description or in the end credits. For example:

Video clip by Jane Smith from Pexels (https://www.pexels.com/video/...). License: Pexels License.

On Social Media

Tag the creator if possible, and include text credit. Example on Instagram:

In Print (e.g., a book or flyer)

Include a credits page or a small text line under the image. Example:

Image: “City Skyline” by Mark Lee, CC BY 2.0

Common Mistakes to Avoid

Even experienced users make errors. Here are pitfalls to watch out for:

  • Incomplete attribution: Forgetting the license or source link.
  • Hidden attribution: Placing credit in a non-obvious place like the page’s HTML comments.
  • Wrong license: Using a CC BY-NC image on a commercial site without permission.
  • Assuming all free images are CC0: Many free sites offer images under different licenses.
  • Not checking the license version: CC 2.0 vs 4.0 may have different requirements.

If you are unsure about an image’s license, it’s safer to use images from reputable sources like paid stock photo sites that provide clear licensing.

Attribution for AI-Generated Images

AI-generated images from tools like Midjourney, DALL-E, or Stable Diffusion have different attribution rules. Many AI platforms allow free use without attribution, but check the terms. For example, Midjourney’s free tier requires attribution for commercial use. Always read the specific license of the AI generator. For more details, see Midjourney vs DALL-E vs Stable Diffusion.

Best Practices for Attribution

  • Always read the license terms before using an image.
  • Keep a record of attributions for each image you use.
  • Use a consistent format across your site or project.
  • If in doubt, contact the creator directly.
  • Consider using a tool like Open Attribute to generate HTML code.

Conclusion

Proper attribution is simple once you understand the license requirements. By giving credit, you support the creative community and avoid legal trouble. Always double-check the license and provide complete, visible credit.
