XML Image Sitemap

Creates an image sitemap to submit to the search engines for better image rankings

vectormapper

Smart Sitemap Lite by VectorMap is a lightweight XML sitemap generator designed for real-world content-heavy sites.
The plugin extracts full image metadata from the WordPress Media Library.
This means search engines receive the actual SEO data you entered: 
– image titles 
– ALT texts 
– captions 
– descriptions
Most sitemap plugins only insert the file name — Smart Sitemap Lite includes real metadata.
It focuses on three things:
<ul>
<li>clean, predictable sitemap URLs;</li>
<li>separation of content types (posts, pages, products, taxonomies, images);</li>
<li>fast generation with minimal overhead, even on large archives.</li>
</ul>
The plugin does not try to be an all-in-one SEO suite. 
It does one job: provides search engines with a clear map of your content.
<h3>Key features</h3>
<ul>
<li>Generates a main sitemap index with links to child sitemaps.</li>
<li>Separate sitemaps for:
<ul>
<li>posts</li>
<li>pages</li>
<li>custom post types (including WooCommerce products)</li>
<li>taxonomies (categories, tags, custom taxonomies – if enabled)</li>
<li>images attached to posts and products</li>
</ul>
</li>
<li>Includes rich image metadata:
<ul>
<li> is taken from the WordPress media title</li>
<li> from the attachment caption</li>
<li> from the ALT text (if present)</li>
<li> from the media description</li>
</ul>
</li>
<li>Works out of the box with most themes and page builders.</li>
<li>Minimal, clear settings page.</li>
<li>No frontend output, no shortcodes needed.</li>
<li>Respects WordPress visibility rules (drafts, private posts, noindexed content etc. are not included).</li>
<li>Compatible with major SEO plugins (Yoast, Rank Math, All in One SEO). 
You can use Smart Sitemap Lite as the primary sitemap or as an additional technical sitemap.</li>
</ul>
<h3>How it works</h3>
After activation, the plugin registers a standard sitemap index URL:
https://example.com/sitemap_index.xml
This index contains links to all child sitemaps (posts, pages, products, taxonomies, images).
Search engines discover this index either from:
<ul>
<li>a direct ping, or</li>
<li>submission in Google Search Console / Bing Webmaster Tools, or</li>
<li>a link from <code>robots.txt</code> (you can add it manually).</li>
</ul>
The plugin uses standard WordPress APIs to fetch content and generate XML, so it respects your existing visibility logic and caching.
<h3>Who is it for?</h3>
<ul>
<li>Site owners who need a clear technical sitemap without a full SEO suite.</li>
<li>Stores and catalogues with many products or images.</li>
<li>Developers and agencies who want a predictable, debuggable sitemap structure.</li>
</ul>
The plugin is built and tested on real-world sites with thousands of attachments and products.
