As of my last update in January 2022, there isn't a specific Visual Studio plugin designed specifically to create image sitemaps directly within the Visual Studio environment. However, you can generate image sitemaps manually by following the steps outlined earlier or by using other tools available online.

While Visual Studio is primarily focused on software development and doesn't include built-in features for SEO-related tasks like creating sitemaps, you can use various third-party tools or plugins outside of Visual Studio to generate sitemaps, including image sitemaps.

Here are a few options you can consider:

1. SEO Plugins: If your website is built on a content management system (CMS) like WordPress, there are SEO plugins available that can help you generate sitemaps, including image sitemaps. Popular SEO plugins like Yoast SEO and Rank Math offer functionality to create and manage various types of sitemaps.
2. Online Sitemap Generators: There are many online tools and services that allow you to generate sitemaps for your website, including image sitemaps. These tools typically crawl your website and generate sitemap files automatically. Examples include Screaming Frog SEO Spider, XML-sitemaps.com, and others.
3. SEO Tools: Some comprehensive SEO tools offer sitemap generation features along with other SEO functionalities. Tools like SEMrush, Ahrefs, and Moz may include sitemap generation as part of their suite of SEO tools.
4. XML Sitemap Generators: There are standalone XML sitemap generators available that can help you create various types of sitemaps, including image sitemaps. These tools may offer more customization options compared to online generators. Examples include the Google Sitemap Generator tool.

Before choosing a tool or plugin, consider factors such as your website platform, budget, and specific features you need for sitemap generation. While there may not be a direct plugin within Visual Studio for this task, you can easily generate image sitemaps using the aforementioned tools and integrate them into your Visual Studio project.
