Image not delivered via cloudflare

Hello
I have installed CLOUDFLARE for my website (5 hours ago) and changed DNS to make it work.
But I don’t see my images beeing delivered by cloudflare.
When I run F12 console network, all my images are delivered by SERVER : APACHE, it should say CLOUDFLARE, why is that ?
Also it does not show CLOUDFLARE SSL, but the SSL I have on my server (the one I had before CLOUDFLARE).
I mean it seems nothing chnaged
Yes my domain is active and DNS are propagated

Hi there,

In relation to the images being served by Cloudflare:

You still have no features enabled.

At the SSL/TLS dashboard on the Edge Certificates section, it shows all the certificates managed by Cloudflare.

Hope this clarifies.

Cheers
