Image crawling from Google blocked by Cloudflare

Dear Cloudflare Community!

I have an E-Commerce store and I have a problem, that Google doesn’t crawl my product images. Googles Bot only crawls the thumbnail product images, which appear on my category pages.

Now I figured out, that Google crawls the product images on my Staging site, which is not with Cloudflare. My developers said, that Cloudflare might be the reason for that, that it blocks image crawling.

Have someone heard of this issue before and could tell me, what I can do?

Thank you so much in advance!
