What Is an Image Sitemap?
An Image Sitemap is an XML file that lists image URLs associated with pages on a website. It gives search engine crawlers structured information about images that may be difficult to discover through normal page links. The file can support image discovery for important visual content, including product photographs, diagrams, and original graphics.

- It extends sitemap information to image resources.
- It supports discovery of images that ordinary crawling may miss.
- It is not the same as an image gallery or image alt text.
How Image Sitemap Works
Image Sitemap information is added to an XML sitemap so crawlers can associate image URLs with the pages where those images appear. A sitemap may identify several images for one page, which gives crawlers a structured route to visual assets. The file does not change the image itself or guarantee that an image will appear in search results.

XML Sitemap entries can include image locations that remain accessible to search engine crawlers. The entries should reflect current, indexable images and should not point to removed files, blocked resources, or unrelated pages. On a site with product photography, location images, or technical diagrams, this information can help search engines find visual content that depends on scripts, galleries, or deeper page structures.
Expert Note
When we review an Image Sitemap, we compare its image locations with the pages and media files that the site actually serves. We check for stale entries, blocked resources, mismatched page associations, and duplicate image references. Our team also inspects whether the sitemap remains accessible to search engine crawlers.
Image Sitemap in Practice: A Real-World Example
For an Adelaide trades business, an Image Sitemap could associate service-page URLs with photographs of completed kitchens, bathrooms, or solar installations. The entries should point to the current image files shown on those pages.
