Free Image Sitemap Generator

Our image sitemap generator crawls your site (up to 200 pages per run, same-origin only, robots.txt aware) and scans each page's HTML for three kinds of images: standalone <img> tags (with lazy-load fallback through data-src, data-lazy-src, and data-original), <picture> containers with responsive <source srcset> (we pick the highest-resolution variant), and <meta property="og:image"> entries (one per page, the social card the page declares for itself).

Every emitted row in the result table carries a provenance badge so you see exactly where each image came from before you publish: img for in-body markup, picture for responsive containers, og:image for page meta. Caption metadata comes from <img alt> only, and only when alt is non-empty after trimming. We never use the page title as the image title, because that would be the same string on every image and the spec asks for honest per-image metadata. Pages with zero detected images are reported in a separate counter rather than emitted as empty url blocks (Google rejects those).

For SEOs

Our tool gives Google's image crawler the structured signal it needs, so you can:

• Surface product photos and editorial imagery in Google Images results
• Catch pages where alt text is missing before submitting to Search Console
• Audit which images Google can actually discover from your HTML

For Developers

Our tool replaces a hand-rolled crawl-and-stitch script, so you can:

• Generate a fresh image sitemap on each deploy without writing the regex
• Verify that lazy-loaded data-src images are being detected
• See exactly which pages were skipped and why, with no silent drops

Why Use Our Image Sitemap Generator

• Honest captions, not invented ones: image:caption comes from alt text only. If alt is empty, we omit the element rather than fabricate one from the page title.
• Per-row provenance badges: The result table shows where every image came from so you can sanity-check before submitting to Search Console.
• Lazy-load and responsive image support: We detect data-src, data-lazy-src, data-original, and pick the highest-resolution variant from srcset automatically.
