Answer 1

Because your pictures are not unique

Answer 2

Maybe I didn’t understand the question a little, but I see images from your site in a Google image search - here.
In addition, it makes sense to add links to images to the sitemap - like this . If Yandex swears at them, then a separate map for Yandex, separately for google.
