To credit a photo correctly, name the photographer, link to the source, and identify the license, and place that information where the reader sees the image. Do this only after you have permission or a license to use the photo in the first place. Credit and permission are two different things, and getting them confused is where most trouble starts.1Office of the Law Revision Counsel. 17 U.S.C. 106 – Exclusive Rights in Copyrighted Works
Credit Is Not Permission
Writing “Photo by Jane Doe” under an image does not make the use legal. Copyright gives the creator exclusive control over reproducing, distributing, and displaying their work, and none of those exclusive rights carry an exception for credited use.1Office of the Law Revision Counsel. 17 U.S.C. 106 – Exclusive Rights in Copyrighted Works You need a license (Creative Commons, stock, or a direct agreement with the photographer) or a legitimate fair use defense before the image goes live. Attribution is an additional obligation on top of that permission, not a substitute for it.
This trips people up most often on social media. Someone reposts a striking photo with “@photographer” in the caption and assumes the tag covers them. It doesn’t. If a demand letter arrives, “I gave you credit” is not a legal defense. Secure the right to use the image first. Then focus on how to credit it.
What a Photo Credit Should Contain
A useful credit answers four questions at a glance: what is the image called, who made it, where did you find it, and what license covers your use. Creative Commons calls this the TASL method (Title, Author, Source, License), and it works as a general framework beyond CC-licensed images.2Creative Commons. Recommended Practices for Attribution
- Title: the name of the image if one exists. Many photos have no formal title, and you can skip this if so.
- Author: the photographer or rights holder, named the way the license or source specifies.
- Source: a link back to where you found the image, or to the photographer’s portfolio, so anyone can verify the license and find the original.
- License: the specific license type, such as “CC BY 4.0” or “licensed via Shutterstock.” For Creative Commons works, link directly to the license deed.
Not every photo requires all four. Public domain images legally require none of them, though naming the photographer and source is standard professional practice.3Creative Commons. Recommended Practices for Attribution – Section: Citing Public Domain Materials Stock photo licenses vary: some require credit, some explicitly say credit isn’t necessary. Read the license terms for the specific image.
Where to Put the Credit
A caption directly beneath the image is the clearest placement: “Photo by Maria Chen / CC BY 4.0” or “Image courtesy of National Archives.” The credit sits where the reader sees the photo, which is the point. On social media, tagging the photographer’s account serves the same purpose, but include their name in the caption text too, because tags break when usernames change.
For sites running many licensed images, a dedicated credits page can supplement individual captions. Some stock licenses permit centralized attribution as an alternative to per-image captioning. Confirm your license allows this before dropping the inline credits, because many Creative Commons licenses expect the credit to appear alongside the image rather than on a separate page.
Alt Text and Watermarks
If you’re publishing on the web, keep screen readers in mind. A credit displayed as visible text near the image does not need to be repeated in the image’s alt attribute; alt text should describe what the image shows, not who took it.4Section508.gov. Authoring Meaningful Alternative Text A credit baked into the image itself as a watermark creates an accessibility problem, because screen readers cannot parse text embedded in an image file. When you overlay text on an image, include that text in the alt attribute as well.
Finding the Photographer and License
Tracking down attribution details is easy when you’re downloading from a stock site or a Creative Commons search tool: the information is right there. It gets harder when a photo arrives by email or you find one on social media with no clear source.
Start with the file’s embedded metadata. Most digital photos carry EXIF data (camera settings, date, GPS) and IPTC metadata, which is specifically designed to hold the creator’s name, copyright notice, and usage terms.5IPTC. IPTC Photo Metadata User Guide On a Mac, view this in Preview under Tools then Show Inspector. On Windows, right-click the file and check Properties, then Details. Note that many social media platforms strip metadata on upload, so it isn’t always there.
When metadata comes up empty, run a reverse image search. Google Images and TinEye let you upload an image and find where else it appears online. The earliest or highest-quality version usually leads back to the original source. If you still cannot identify the creator after checking metadata and running a reverse search, contact whoever sent you the image and ask. Using a photo when you cannot identify the rights holder is a gamble with a bad payoff.
If you are the photographer distributing your own work, embed your name and license terms into the IPTC fields before sharing. Adobe Lightroom, Photoshop, and free tools like ExifTool write to these fields. It won’t stop someone from stripping the data, but it creates a record showing you asserted copyright from the start.
How the License Shapes the Credit
The license attached to a photo determines both whether you can use it and how you have to credit it.
Creative Commons
Creative Commons offers six license types, all of which require attribution. Every CC license carries the “BY” element, meaning credit must be given to the creator.6Creative Commons. About CC Licenses The licenses differ in what else they restrict:
- CC BY is the most permissive. Use it for anything, including commercial projects, as long as you give credit.
- CC BY-SA carries the same freedom, but modifications must be released under the same license.
- CC BY-NC requires credit and limits use to noncommercial purposes.
- CC BY-ND allows commercial use with credit but forbids altering or adapting the image.
- CC BY-NC-SA and CC BY-NC-ND combine the noncommercial restriction with either share-alike or no-derivatives.
CC0 is different. It’s a public domain dedication rather than a license, and it carries no legal requirement to give credit.7Creative Commons. CC0 Crediting a CC0 source is still good practice, particularly in academic or journalistic contexts where sourcing is expected regardless of copyright status.
Public Domain
Works in the public domain are free of copyright restrictions entirely. As of January 1, 2026, works published in 1930 entered the U.S. public domain, along with sound recordings from 1925.8Duke University School of Law. Public Domain Day 2026 Legally you can use these without permission or attribution, but crediting the source remains standard practice, both for professionalism and to help readers find the original.
Stock Photo Licenses
Stock licensing generally splits into two categories. Royalty-free licenses charge a one-time fee and grant broad, ongoing rights; many do not require per-use attribution, though some platforms request it. Rights-managed licenses are more restrictive, granting specific usage rights for a defined time, purpose, and sometimes geographic region, with pricing that varies by use. Read the specific license agreement, because attribution and usage terms vary significantly between platforms and even between individual images on the same platform.
Editorial Versus Commercial Use
Photos licensed for editorial use can illustrate news stories, commentary, or educational content, and they may include recognizable people, logos, or private property without model or property releases. That same image typically cannot appear in advertising, marketing, or product packaging. Commercial use generally requires model releases from identifiable people and property releases for recognizable private locations. Mixing these up creates exposure that goes beyond a credit issue, because right-of-publicity claims can come from the people in the image.
Fair Use Doesn’t Replace a Credit
Fair use lets you use a copyrighted photo without permission in limited circumstances such as criticism, commentary, news reporting, or education. Courts weigh four factors: the purpose and character of the use, the nature of the copyrighted work, the amount used, and the effect on the market for the original.9Office of the Law Revision Counsel. 17 U.S. Code 107 – Limitations on Exclusive Rights: Fair Use
The amount-used factor is where photos trip people up. Unlike quoting a paragraph from a book, displaying an image usually requires reproducing the whole thing, which makes fair use for photographs narrower than many people assume. Fair use is also a defense argued in court, not a bright-line rule you can rely on in advance. Even when you’re relying on fair use, credit the source: courts have noted that failing to credit weighs against a fair use finding.
If You Get a Demand Letter
Copyright infringement carries financial penalties that can dwarf the cost of simply licensing the image. Statutory damages range from $750 to $30,000 per work, and up to $150,000 per work for willful infringement.10Office of the Law Revision Counsel. 17 U.S. Code 504 – Remedies for Infringement: Damages and Profits Professional photographers and stock agencies typically register their catalogs, which is what unlocks those statutory ranges and attorney’s fees; unregistered works are limited to actual damages.11Office of the Law Revision Counsel. 17 U.S. Code 412 – Registration as Prerequisite to Certain Remedies for Infringement
If a photographer or stock agency sends you a demand letter, don’t ignore it, but don’t panic. These letters often demand several thousand dollars for a single image, and the amount is frequently negotiable. A practical approach:
- Remove the image immediately. This won’t undo past liability, but it stops additional damages from accruing and shows good faith.
- Verify the claim. Confirm the sender actually owns the copyright or represents the owner, and ask for proof of registration if anything looks questionable.
- Research fair market value. Look up what comparable images sell for on major stock platforms. A photo that licenses for $10 doesn’t justify a $5,000 demand.
- Respond professionally. Acknowledge the situation, confirm the image is down, and if appropriate propose a settlement based on fair market value rather than the inflated figure.
- Consult an attorney if the demand is large or the sender escalates. Some demand letters come from operations sending thousands of identical letters hoping people will pay without questioning the amount.
Crediting AI-Generated Images
AI-generated images occupy an awkward space in copyright law. The U.S. Copyright Office has stated that images generated solely through AI prompts, without meaningful human creative control, are not eligible for copyright protection. When a human selects, arranges, or meaningfully modifies AI output, the human-authored elements can receive protection.12United States Copyright Office. Copyright and Artificial Intelligence Part 2: Copyrightability Report
When registering a work that includes AI-generated material, the Copyright Office requires applicants to disclose that fact and describe the human author’s contribution. Major platforms are also adopting the C2PA content credentials standard, which embeds cryptographically signed provenance data (including whether AI was used) into image files.13C2PA Specifications. C2PA and Content Credentials Explainer
In practice, credit the tool and note any human modifications: “Generated with Midjourney” or “Created using DALL-E 3, edited by [your name].” Since fully AI-generated images may not be copyrightable, this isn’t strictly a legal requirement in most contexts, but it has become an editorial norm. Omitting it risks credibility more than it risks a lawsuit.
