Do you mean my discourse doesn’t have permission to access S3 Bucket of other 3rd party free CDN images sites?
If i can access an image in a browser, then discourse can too, and already discourse is optimising the images i share using hot-links. So i think we need this feature for sure.
i updated my reply above for discourse CDN comparison, please check.
What other cheapest way do you suggest me to host my images in bulk? Because i am afriad that if my site get millions of topics means billions of images, and my Discourse site backup will start getting bigger bigger and very hard and expensive to manage/scale and migrate. What would i do in that case then?
