The Complete Image Sitemap plugin will generate an XML Sitemap for all images, including Woocommerce products.
Image sitemaps inform search engines about image content location on your website.
The Complete Image Sitemap plugin will generate a sitemap for your WordPress-based website with the image URLs that are attached to your posts: both blog posts, pages and other types, such as Woocommerce products.
It is also possible to specify the license for all images on your website. Be careful before you donate everything to the public domain though :-).
The plugin is written by Herbert van-Vliet of Remark.no, and is based on Amit Agarwal’s image sitemap plugin.
Here’s how you can install the plugin:
Check Google Webmaster Tools.
The sitemap is stored as “sitemap-images.xml” in the root of your website.
This is most likely caused by the fact that you do not have write permission on the website webroot. Use chmod to set the necessary permissions. Do NOT set that to 0777, unless you know what you are doing.
