How to Credit and Attribute Free Images
Many free images are free only if you credit the creator, and a missing or incorrect credit turns a legal image into an infringing one. The good news is that attribution is simple once you know what a credit needs to contain and where to put it. This guide walks through it step by step, so you can use credit-required images with confidence and keep a clean record that protects you later.
When Attribution Is Required
Not every free image needs a credit. Public domain and CC0 images can be used with no attribution at all, which is part of why they are so convenient. Creative Commons BY licenses, on the other hand, require credit as a binding condition, and many free icon sets and some platform licenses ask for it too. The only way to know is to read the license for the specific image, because two pictures from the same site can carry different terms.
When a license does require attribution, treat it as mandatory, not optional courtesy. The permission to use the image is granted in exchange for the credit, so skipping the credit means you no longer have permission, even though the download cost nothing.
Step by Step
Step 1: Check whether attribution is required. Open the license for the image and look for whether credit is mandatory. If it is public domain or CC0, you are free to skip attribution. If it is a Creative Commons BY license, an icon set that asks for credit, or a platform that requires it, plan to include one.
Step 2: Gather the required details. A complete credit usually needs four things: the creator's name, the title of the work if it has one, a link to the source, and the name of the license. Collect these while you are on the source page, since tracking them down later is far harder than copying them now.
Step 3: Write the credit in the right format. Combine the details into a clear line, typically the title and creator, the source, and the license, with links wherever the medium allows. A common pattern is: "Title" by Creator, via Source, licensed under [license name]. Follow any specific wording the license requests, since some specify exactly how the credit should read.
Step 4: Place the credit where it can be found. Put the attribution somewhere a viewer can reasonably reach it: directly beneath the image as a caption, in a small credit line, or in a dedicated credits or image sources section. The standard is that the credit is reasonably visible and associated with the image, not buried where no one would look.
Step 5: Keep a record of your sources. Maintain a simple list of every image you use, where it came from, and its license. This protects you if a question ever arises, makes it easy to update or replace images later, and ensures you can reproduce a required credit even if the original page disappears. A spreadsheet is enough.
A good attribution generally names the creator, the work, the source, and the license, with links where possible. When in doubt, give more credit rather than less. Over-crediting never causes a problem, while under-crediting can.
Attribution in Different Places
The right placement depends on the medium. On a web page, a caption under the image or a credits section at the end both work well, and links can point straight to the creator and license. In a video, credits typically appear in a description or an end card. On social media, where space and links are limited, name the creator in the caption as clearly as the platform allows. The principle is constant even when the format changes: make the credit findable and accurate.
If you use many credit-required images across a site, a single, well-organized image credits page that lists each image and its attribution is a clean solution. It keeps individual pages uncluttered while still meeting the requirement, and it gives you one place to maintain as your library grows.
