This new Images binding looks great! Definitely will simplify multiple parts of my graphics workflow

One question, is there a limit to the number of

.draw()

.draw()

commands that can be done in a single request? Through the existing

draw: []

draw: []

method, I have been limited to ~70 layers due to 16KB header limit, hoping this will be able to get around that but not sure if the binding is just doing a

fetch()

fetch()

underneath

Most bindings are doing fetches underneath, but whether it uses the same format (passed in the header) will depend on the implementation.

All good, I have a batching method that works fine (draw 25 layers, save result, draw next 25 layers on saved result), but this should still simplify that setup a lot

i figured but when they said image bindings i was expecting the entire service
like https://developers.cloudflare.com/images/upload-images/upload-file-worker/

Cloudflare Docs

Upload via a Worker · Cloudflare Images docs

You can use a Worker to upload your image to Cloudflare Images.

SSilvan i figured but when they said image bindings i was expecting the entire service ...

1

1984 Ford Laser•2/25/25, 11:37 AM

Usually they're expecting that the images will be stored somewhere outside Images itself, to be transformed by the binding. I would like your suggestion to be added, as well as listing and getting images directly through the binding instead of needing to pull from R2 or similar

S

Silvan•2/25/25, 11:39 AM

yea i will have to do things like that soon still have to decide if images alone can even do what i want. else its just r2

1

1984 Ford Laser•2/25/25, 11:58 AM

so the Images binding allows a maximum of 10 transforms per call (

"IMAGES_TRANSFORM_ERROR 9432: Bad request: 10 \"transforms\" maximum"

"IMAGES_TRANSFORM_ERROR 9432: Bad request: 10 \"transforms\" maximum"

). In the docs there is this note for error 9432:

 The Images Binding is not available using legacy billing. Your account is using the legacy Image Resizing subscription. To bind Images to your Worker, you will need to update your plan to the Images subscription in the dashboard.

Hi, i have a question about the rules and R2, I have a rule that redirects all traffic on my domain.

Will this custom domain thing overwrite the CloudFlare Rule?

Hi. I use this a lot when debugging my Pages function - npx wrangler pages deployment tail --environment "preview". But, it often just closes the connection and exits after it spits out a few debugging statements. Is there some type of timeout that I need to configure to keep it listening until I'm done debugging?

M

matt•2/25/25, 11:25 PM

in a pages function, can I connect to a cloudflare tunnel if there are no public dns records?

M

matt•2/25/25, 11:49 PM

looks like you need either a dns record or a load balancer, since dns records are public... can i use a load balancer and route to the tunnel if the incoming request contains a header secret?

P

Peps•2/26/25, 2:18 AM

you could totally do that. I forgot if the free plan has access to WAF, but if it does, you could simply create a WAF rule that blocks all requests to that specific subdomain when it doesn't contain a specific header with a pre-determined value

P

Peps•2/26/25, 2:19 AM

another option would be using Cloudflare Access and making use of a service token to programmatically access the protected app (which would mean just setting 2 headers basically)
https://developers.cloudflare.com/cloudflare-one/identity/service-tokens/

M

matt•2/26/25, 2:26 AM

cheers @Peps

I ended up just using a load balancer rule since I already had one in place to route between my Pages app and some backend routes on my k8s service that users need to access. i just added the extra condition to the custom rule and voilà!

although the secret does come through in plaintext in the UI, I will probably need to switch to your method if im looking for something more secure
