Our Image License Attribution Policy

Understanding Image Attribution and Licensing

Every photo on a healthcare website tells a story - but using images without proper permissions opens the door to legal trouble. For a medical tourism platform like Istanbul Care, where visual media drives patient trust, understanding how image licensing and attribution work isn't optional.

What's the difference between a license and attribution?

A license is the legal permission granted by the copyright holder to use an image under specific conditions. Attribution is one of those conditions - it means giving credit to the creator in the way they request. You can have a license that requires no attribution (e.g., CC0 public domain) or one that demands it (e.g., Creative Commons Attribution 4.0). If you use an image under a CC BY license and forget to credit the photographer, you're technically infringing copyright.

• Creative Commons (CC) licenses - the most common open licenses. Variants include CC BY (attribution only), CC BY-SA (share alike), CC BY-NC (non-commercial). Always check the specific license icon.
• Public domain - no restrictions. Works marked as CC0 or those whose copyright has expired fall here. No attribution required, but it's still good practice.
• Royalty-free - you pay once to use the image multiple times, but the license still has terms (e.g., no resale, no offensive use). Attribution may or may not be required.
• Rights-managed - negotiated per use. Strict limits on medium, geography, duration. Almost always requires credit.

How to attribute correctly

A proper attribution includes four elements (the TASL formula): Title of the work, Author, Source (where you found it), and License (the specific license version). For example: "Istanbul Bosphorus at Sunset" by Ahmet Yılmaz, licensed under CC BY 4.0, via Unsplash. Place the credit close to the image - in a caption, on the same page, or in a clearly labeled credits section.

On Istanbul Care's website, every photo in gallery pages, blog posts, and procedure descriptions must carry a visible credit if the license requires it. A separate "Image Credits" page works for bulk attribution, but the connection between image and credit must be unambiguous.

Practical steps for Istanbul Care

Before uploading any visual:

How Istanbul Care Manages Image Licenses

Istanbul Care runs every image it uses through a license check. No photo, illustration, or video goes live until the rights are confirmed and the required attribution is attached. The company draws from three main sources: its own commissioned photography, rights-cleared stock libraries, and Creative Commons‑licensed work submitted by third parties. Each source has a distinct handling procedure.

Tracking License Types

For stock images, Istanbul Care keeps a internal registry that records the vendor, license type (royalty‑free, rights‑managed, or editorial‑use), and the expiry date if any. Creative‑commons assets are sorted by the specific CC version - CC0, CC BY 4.0, or CC BY‑SA - because the attribution requirements differ. CC0 images need no credit line. CC BY images must name the creator, the license, and link back to the source. Istanbul Care's content team verifies every CC image's metadata before publication to catch mislabeled or improperly-licensed files.

Commissioned photography is handled through signed work‑for‑hire agreements that grant Istanbul Care unlimited use. The contracts explicitly state that the photographer retains no residual rights and that the organisation can crop, overlay text, or repurpose the image without further approval.

Attribution in Practice

When an image requires credit, Istanbul Care places the attribution directly below the image or, for inline images, as a data-attribution field in the page's markup. The format follows the recommendations of the specific Creative Commons license:

• CC BY 4.0 - "Photo by Laura Schmidt / CC BY 4.0" with a hyperlink to the original work.
• CC BY‑SA 4.0 - Same format but notes "ShareAlike" so downstream users know the license transfers.
• CC0 - No attribution required, though the company still lists the source in its internal asset log.

Stock images from paid services (Shutterstock, iStock) are attributed only when the license explicitly demands it. most royalty‑free stocks do not require a credit line. Istanbul Care nevertheless notes the vendor in its metadata for auditing purposes.

To keep the system consistent, the company uses a simple spreadsheet that maps each image URL to its license class, attribution text, and renewal date. A quarterly review flags any images whose license term has expired.

Different Types of Creative Commons Licenses

Creative Commons (CC) licenses give photographers, designers, and content creators a simple way to share their work while setting clear terms for reuse. For a medical tourism platform like Istanbul Care, understanding these licenses is essential to staying compliant when publishing images on the website. Each CC license type has specific rules around attribution, commercial use, and derivative works.

CC0 - Public Domain Dedication

CC0, often called "no rights reserved," means the creator has waived all copyright claims. Anyone can copy, modify, distribute, or use the image commercially without asking permission. Istanbul Care may use CC0‑licensed photos without attribution, but listing a credit line is still a best practice for transparency. Around 30% of free stock image libraries operate under CC0.

CC BY - Attribution Required

This is the most flexible standard license. Others can reuse, adapt, or sell the work as long as they credit the creator. A proper attribution example would be: "Photo by John Doe, CC BY 4.0." Istanbul Care's image licence attribution policy follows this model whenever a CC BY image is featured.

CC BY-SA - ShareAlike

Derivatives must carry the same license as the original. If Istanbul Care modifies a CC BY‑SA image, the new work must also be released under CC BY‑SA. This protects the community but limits how the platform can package visual assets for clients.

CC BY-NC - Non‑Commercial Only

These images cannot be used for commercial purposes. Because Istanbul Care is a for‑profit company, CC BY‑NC photos are generally not suitable unless the usage falls under fair use or editorial commentary. The policy explicitly excludes NC‑licensed visuals from marketing materials.

CC BY-ND - No Derivatives

Modifications are forbidden. The image can only be used as‑is. For a health tourism site that often resizes, crops, or overlays text, ND licenses create a practical hurdle. The team typically avoids them for hero banners but may use them in direct‑quote sections.

How Istanbul Care Chooses a License Type

Before an image goes live, the content team checks its CC designation against internal guidelines:

• CC0 - preferred for speed and flexibility.
• CC BY - used with a visible credit line.
• CC BY-SA - accepted but flagged for share‑alike obligation.
• CC BY-NC / CC BY-ND - avoided unless editorial context demands it.

When a creative commons image requires attribution, the credit appears directly beneath the photo or in a site‑wide attribution section. This keeps the process consistent and legally sound for every page on the platform.

How to Give Proper Attribution for Images

What Proper Attribution Looks Like

Attribution simply means giving credit to the creator of an image you did not produce yourself. Under Istanbul Care's licensing policy, every image that does not belong to the clinic - whether sourced from a stock library, a Creative Commons repository, or directly from a photographer - must carry a clear, visible credit line. The goal is to let any visitor know who made the image and under what terms they may reuse it.

The Required Elements for Istanbul Care

To meet the standards of image licence attribution on this site, each credit must include four pieces of information whenever possible:

• Creator's name - the photographer or designer who holds the copyright.
• Title of the work - if the image has a designated title, include it in quotation marks.
• Source URL - a direct hyperlink back to the original work online.
• Licence type and link - e.g., "CC BY 4.0" with a link to the licence deed.

When an image comes from a stock agency like Shutterstock or Adobe Stock, the attribution line should state the agency and the specific licence purchased. For example: "Photo by John Doe via Shutterstock (Standard Licence)." In the case of Creative Commons works, the attribution must follow the format recommended by the licence steward.

Real Attribution Examples

Here is how a properly formatted credit looks on our website:

Common Mistakes That Break Compliance

A few regular errors trip up even experienced editors:

• No credit at all - the most obvious violation. Every non-owned image needs attribution.
• Incomplete credits - adding only the creator's name without the licence link or source URL.
• Broken links - a hyperlink that leads nowhere fails the "accessible" requirement.
• Attribution hidden in the footer - credits must appear near the image itself, not buried at the bottom of the page.

Istanbul Care's compliance team checks these details before any page goes live. If you are reusing content from the site, you must maintain the original credit exactly as shown.

Why It Matters Beyond Legal Obligation

Clear image licence attribution builds trust with readers. When a visitor sees a proper "Photo by…" line, they know the clinic respects copyright and transparency. That trust carries over into the medical information we present.

Does a CC0 License Require Attribution?

No. Under a CC0 license, the creator has waived all copyright and related rights worldwide. You are not legally obligated to credit them. That's the whole point of the "No Rights Reserved" designation - it's as close to public domain as modern licensing gets.

Yet many professionals still choose to attribute CC0 works out of habit or courtesy. The Metropolitan Museum of Art, for instance, releases over 375,000 images under CC0 but includes a suggestion to "credit the museum" on its page. They don't enforce it - but it's a nice gesture. On platforms like Pixabay and Unsplash, contributors often write "No attribution required" in the description. Even so, around 68% of graphic designers say they add credit lines to CC0 images anyway, mostly to avoid confusion down the line.

The photographer never complained. Legally, they couldn't. Under CC0, all rights are waived, meaning the café didn't owe a single credit line. That's the cleanest way to reuse visual media without legal strings.

When You Might Still Want to Provide Credit

Even without a legal requirement, some creators mention "I would appreciate a credit but it's not mandatory." This is a non-binding request.
