Hi @vmajor,
Thanks for giving Alt Text Tools a try!
The plugin should include all images that are actually used in your content — there’s no artificial limit, or anything like that. So if an image is in the media library, but isn’t actually used anywhere in the content, it won’t show up in the CSV.
I see you’re using WooCommerce… I’m actually not sure if it will show the alt text for product images, since those aren’t set manually when adding the images. I’m also not sure if Woo will use the Alt Text that’s configured in the media library, or if it will auto-generate based on product details. I’d suggest you test on a specific product/image – check the alt text on the image on the product page, and then add the alt text to the image in the media library and see if Woo updates it on the product page?
If you do need to go through and add alt text for images in the media library, you can do that manually – or The Blog Fixer also has a helpful product for this… it’s a bit more robust than our CSV export tool. https://www.blogfixer.com/image-alt-text-generator-fix/
Hope that helps!
