Cloudflare images blocked by Gmail

Hey guys, I have a couple of images hosted in cloudflare and am using them to send email. But google is blocking them with the URL like this: https://ci3.googleusercontent.com/proxy/8lFXl1duOMpVE88qEeHUVkrvBpurG0xOjXK6EAd1nvWo0QK-AMbkHJRXkZ59cLXn45vAAMZLJxmwhN1T9u_rrSjMjgpZlj8wR_wUuKvsuSJeTHFMHrtvA6t8FBzC48-J19FEbQKa9pkmoP6Go0cScq7BxXJ6jtQAshXc7z10aUz6M78fUoKVng4tA7YzTGPxnXEUxj2uo0YESFkl25D6T5bVsrunPPd8Ug=s0-d-e1-ft#{MY_CLOUDFLARE_URL}

I did search for it in the web and found some articles but none explain clearly on what to do. Please suggest me what to do here.

The articles I referred to are here:

Cloudflare blocking images in emails

You were right about them being blocked by Hotlink Protection. I added a firewall rule to Bypass the two URLs; but for some reason the images are still being blocked. Here is a screenshot of the rule: https://i.imgur.com/3uzMgVj.png
