画像サイトマップは、特に他の方法では Google が検出できない可能性がある画像(JavaScript コードでサイトがアクセスする画像など)を含むサイト上のその他の画像について Google に伝える方法です。画像サイトマップを別に作成しても、既存のサイトマップに画像サイトマップのタグを追加してもかまいません。どちらの方法でも Google は読み取ることができます。

In some cases, the image URL may not be on the same domain as your main site. This is fine, as long as you verify both domains in Search Console. If, for example, you use a content delivery network such as Google Sites to host your images, make sure that the hosting site is verified in Search Console. In addition, make sure that your [robots.txt](/search/docs/crawling-indexing/robots/intro) file doesn't disallow the crawling of any content you want indexed. |\n\nDeprecated tags and attributes\n\n\nWe removed the following tags and attributes from our documentation:\n`\u003cimage:caption\u003e`, `\u003cimage:geo_location\u003e`,\n`\u003cimage:title\u003e`, `\u003cimage:license\u003e`.
