How do I use Creative Commons images from Flickr?

Open the original Flickr page and read the exact license terms for that specific image. A Creative Commons badge means the person who posted it claims to hold copyright and has chosen a particular CC tool. It does not verify that claim. The badge also does not override Flickr's own terms of service or confirm that every component of the image is covered by the license shown. Record the creator, source URL, exact license deed and the date you checked before you use the image. That is how you use Creative Commons images from Flickr correctly.

Flickr's search offers a filter labelled "Commercial use & mods" with options such as "Attribution-NonCommercial-ShareAlike 2.0 Generic." That filter returns images whose poster selected that exact license code from a dropdown during upload. It does not verify the poster's authority. The poster may not be the creator, may not have cleared third-party elements, or may have applied the wrong license class entirely. The filter is a convenience, not a legal clearance.

Open the image's full page on Flickr. Below the image, the license appears as a linked name such as "Some rights reserved" or "Public Domain." Click that link. It should open the corresponding Creative Commons deed page or the Public Domain Mark deed. The deed page shows the human-readable summary and links to the legal code. If the link points to an older version, 2.0 or 3.0, the terms differ from the 4.0 International suite. Version 4.0 is what the current suite uses, but you cannot upgrade someone else's license unilaterally.

Record the license version and the exact deed URL. A screenshot of the full image page and the deed page is evidence. Without it, you have no proof of what license was offered on the date you downloaded.

Do not rely on a repost, a search thumbnail, or a third-party site that rehosts the image. Open the original Flickr page. The URL pattern is flickr.com/photos/[username]/[image-id].

What to Record Before You Download

• Creator name and attribution party, exactly as shown on the page.
• Source URL, including the image ID.
• Exact license name and version, e.g. "CC BY-NC-SA 2.0 Generic".
• The deed URL that the license link points to.
• Any notices the poster has added: copyright notice, warranty disclaimer, exclusions of unlicensed content.
• Date and time of your download.

Take a screenshot of the image page showing the license badge and any notices. The 4.0 legal code requires you to retain "identification of the creator and designated attribution parties; a copyright notice; a notice referring to the license; a warranty disclaimer; and a URI or hyperlink to the material where reasonably practicable." Those are not optional. A screenshot captures them if the page changes later.

If the poster has not supplied a creator name, the license still covers the image, but your attribution should state that the creator is unknown and note the source. Do not invent a name.

Flickr provides a field for the image title, a field for the description, and an "Owner" name that may or may not be the creator. The 4.0 attribution clause does not separately require the work's title, although including it is useful practice. You must attribute the creator, link to the source, indicate changes, and link or refer to the license. Flickr does not enforce any of this.

The Flickr Terms Conflict

The decisive exception to watch for is Flickr's own terms. A CC badge on Flickr does not override terms that grant Flickr a sublicense over your uploads or that restrict downloading through technological measures. Under 4.0 you "may not impose additional legal terms or effective technological measures that restrict another recipient's exercise of the licensed rights." If Flickr's platform applies DRM or exclusive sublicensing clauses, the CC badge alone does not resolve that conflict. Check Flickr's current terms of service before relying on the license.

Adaptation and ND

If the license is ND, you may share the image unchanged but you may not share adapted material. Changing format alone, saving a JPEG as PNG, is not adaptation under 4.0. Cropping, editing, or combining with other images may or may not be an adaptation; applicable copyright law decides. Translation is normally an adaptation. Synchronising music with a moving image is expressly Adapted Material. Do not guess.

License	Share Unchanged	Share Adapted	Commercial Use	Attribution Required
CC BY 4.0	Yes	Yes	Yes	Yes
CC BY-SA 4.0	Yes	Yes, must use BY-SA 4.0 or compatible	Yes	Yes
CC BY-ND 4.0	Yes	No	Yes	Yes
CC BY-NC 4.0	Yes, non-commercial	Yes, non-commercial	No	Yes
CC BY-NC-SA 4.0	Yes, non-commercial	Yes, non-commercial, must use NC-SA	No	Yes
CC BY-NC-ND 4.0	Yes, non-commercial	No	No	Yes

NonCommercial

Version 4.0 defines NC as "not primarily intended for or directed toward commercial advantage or monetary compensation." The identity of the user, business, nonprofit, school or individual, does not decide the issue by itself. Advertising, sponsorship, fundraising, internal business use and mixed purposes require context. Do not invent a bright-line rule. If your planned use has material commercial risk, get separate permission or local legal advice.

ShareAlike

The SA condition is triggered when Adapted Material is shared, not when unchanged material merely appears beside other separate works in a collection. If you adapt a BY-SA image and share the adaptation, you must apply BY-SA 4.0 or a license Creative Commons has formally named as compatible. The official compatibility list controls. Do not assume two SA licenses are compatible. Creative Commons lists one-way compatibility from BY-SA 4.0 to GPLv3 for adapted material; this does not turn a CC license into a software license or create compatibility in the reverse direction.

CC0 and the Public Domain Mark are not two more licenses in the six-license suite. CC0 is a public-domain dedication with a waiver, a fallback license where waiver is not effective, and a non-assertion promise limited to remaining Copyright and Related Rights. It aims to remove copyright and related-right conditions as far as the affirmer is legally able. PDM changes no rights; it marks material believed to be free of known copyright restrictions worldwide. Neither tool guarantees that privacy, publicity, trademark, patent, contract, cultural-heritage or other law permits a use.

Credit is not a CC0 legal condition, but citation, research integrity, community norms and avoidance of false authorship can still make credit proper. On Flickr, a CC0 or PDM designation still requires you to check that the poster controlled the rights they waived. A screenshot of the deed page and the image page is the same evidence you need for any other designation.
