Image backlinks come from sites that reuse your charts and photos. How to set up image pages, find uncredited copies, ask for credit, and what AI search uses.
Image backlinks come from other sites that use your charts, diagrams or photos and link back to you as the source. You get them in two ways: by publishing images people want to reuse, and by asking for credit from sites that already use your images without a link. Below is how to set up an image so it earns credit, how to find sites using your images, what to send them, and what helps an image show up in AI search, which is a separate job.
Where image links come from
Image links come in three main forms:
- Reuse with credit. A writer finds your chart or diagram, puts it in their article and links to your page as the source.
- Reclaimed credit. A site already uses your image but gives no link, or credits you by name only. You ask them to add the link.
- Licensing. A publisher asks to use a photo or graphic, and the credit link is part of the terms.
All three depend on the same thing: an image good enough that someone wants it on their page. Original data turned into a chart, a clear diagram of a process, a map, or photos you took yourself give a writer something they cannot get anywhere else. A stock photo that thousands of sites already use gives them no reason to credit you. Our post on link earning versus link building covers which assets earn links and why.
Set up the page each image lives on
The page that hosts the image is the page you want links to point at, so give each important image a proper home.
- Use a standard HTML image element. Google's image SEO best practices say standard image elements help crawlers find images, and that "Google doesn't index CSS images."
- Place the image near text that explains it. Google says it extracts information about an image from the page, including captions and image titles, and asks you to place images "near relevant text".
- Write alt text that describes the image. Google calls alt text "the most important attribute" for image metadata and warns that filling it with keywords "may cause your site to be seen as spam."
- Use a short, descriptive filename. Google says the filename gives "very light clues" about the subject, and its own example rates my-new-black-kitten.jpg above IMG00023.JPG.
- Keep one URL per image. Google suggests referencing an image with the same URL across your site so it can cache and reuse it.
Alt text can also bring image search traffic. HubSpot's blog team says that beginning in 2018 it focused more on alt text as part of a new SEO strategy, and image traffic grew 779% in less than a year, which resulted in 160,000 more organic views.
Tell people how to credit you
Under the image, add a short credit line people can copy, with the image title, your name or brand, and a link to the page. That mirrors what Creative Commons recommends for attribution: title, author, source and license, which it shortens to TASL. If you want the link, say so in the credit line, and make the source link part of it.
You can also put the license in the image metadata. Google's image metadata documentation says license details can make an image eligible for the Licensable badge in Google Images, which links to the license. You can add it with ImageObject structured data, using properties such as license, acquireLicensePage and creditText, or with IPTC photo metadata embedded in the file. Google notes that IPTC metadata can "move from page to page while still staying intact", which helps when your image is copied. Google also says it "does not guarantee" that this metadata will show in results.
Find sites using your images without a link
Reverse image search shows where an image appears online.
- Search with Google Lens. Google's help page on searching with an image says results can include "Websites with the image or a similar image". You can upload the file, drag it into the search box, or paste the image URL.
- Search with TinEye. Its tutorial says it can find out "how it is being used" and whether modified versions exist. Sort by Newest to see recent copies, and use the domain filter to check one site.
- Open every result. Note whether the page links to you, credits you by name only, or gives no credit at all.
- Keep the pages that are relevant to your topic and look like real sites. Skip scraper pages and image farms, since a link from them is not worth the email.
TinEye says it may not have found every copy, so run the same searches again every month or two for your most shared images.
Ask for the credit link
Write to the editor or site owner, not a general inbox, if you can find them. Keep it short and friendly, and assume the missing link was an oversight. Here is a template:
Hi [name], thanks for using our chart of [topic] in your article [title]. We made it from [where the data came from]. Would you add a source link to [page URL] under the image? It helps readers find the full data. If you need a larger version or the numbers behind it, I can send them.
Offer something useful, such as a larger file, an updated version or the raw data. If they say no, or do not reply after one follow-up, move on. Whether to pursue a licensing fee or a takedown is a separate decision, and it is worth getting legal advice before you threaten either.
Embed codes and Google's rules
If you offer a box of embed code with a link back, keep that link within Google's rules. Google's spam policies list "Keyword-rich, hidden, or low-quality links embedded in widgets that are distributed across various sites" as link spam. So make the link in your embed code visible, point it at the page the image came from, and use the image title or your brand name as the anchor, not a keyword you want to rank for.
Track the links you win
Keep a list of every page that adds credit, with the date. Links can disappear when pages are edited, so check the list now and then. SerpCrest's bulk DoFollow checker checks a list of URLs for live, dofollow and indexed status.
Image links and AI search are different jobs
Getting links to an image and getting an image used in an AI answer are solved by different work.
Ranking well is also a weaker route into AI Overviews than it was. In a March 2, 2026 update, Ahrefs found that 37.9% of URLs cited in AI Overviews also appeared in the first 10 results blocks, compared with about 76% in its July 2025 study. That data is about ranking, not image links, so it does not show that image backlinks change AI citations either way.
What does help Google understand an image is on your own page. Google says it "uses alt text along with computer vision algorithms and the contents of the page to understand the subject matter of the image." So the setup steps above do double duty: they help people credit you, and they give Google the text it uses to understand the image. If AI visibility is your main goal, our post on schema markup and AI citations covers what structured data can and cannot be shown to do.
Our advice: build an image link campaign for the links and referral traffic it brings, not as a shortcut into AI answers. Start this week by running your three most popular images through Google Lens and TinEye, and send a credit request to every relevant site that uses one without a link.
