I would recommend moving these to be under your own domain, at which point you can use something like Transform Rules.
You’ll currently be using the dedicated
imagedelivery.net domain but all of your images are actually available under your website in the
As an example, here’s a blob: https://imagedelivery.net/kdRbTDgaPUHq8PGsHZ1fKA/4d263d6d-cdb6-4781-fe91-a4a45ee1bc00/public
If I wanted to serve this under my domain, it would be https://kian.org.uk/cdn-cgi/imagedelivery/kdRbTDgaPUHq8PGsHZ1fKA/4d263d6d-cdb6-4781-fe91-a4a45ee1bc00/public

We can now create a Transform Rule to modify the
Cache-Control response header that’ll allow us to set a much longer cache on the browser. You can create these here: https://dash.cloudflare.com/?to=/:account/:zone/rules/transform-rules/
31536000 translates to 1 year, the maximum value. You can read about the other options available in the

Now if we check that image again, it has the
Cache-Control value that we set.
