Hii!
In my opinion to create an image sitemap, I recommend trying out Screaming Frog SEO Spider. It's a versatile tool that not only generates regular sitemaps but also includes functionality for image sitemaps. Simply crawl your website using the tool, and you'll find options to export both XML and image sitemaps. I also use this tool for my website : informatica BDM Training And it's amazing.
Hope this helps!
