The discussion is about how image links are generated in Discourse. TheBestPessimist asks if it’s possible to link to an image using the “upload link” (), and how to find other versions of the image, such as retina or mobile versions. zogstrip explains that the upload link is a custom URL scheme that only works within the same Discourse instance, and that there are original and thumbnail versions of images generated to support different pixel ratios.
TheBestPessimist clarifies that they are interested in getting the original link, and notes that the link provided by “Copy link address” is not the same as the original link on S3. zogstrip explains that the two links are the same file, but one is on the CDN and the other is on S3.
Finally, codinghorror provides a simple solution to the problem: clicking or tapping on the image and then clicking or tapping the download link at the bottom will provide the original image link.
can i link somehow to the image via the “upload link”:  (eg: https://meta.discourse.org/uploads/nkjFnpawJaOanmycDbIXVG4jlkn.jpeg) => i would expect that discourse will redirect me to the correct url afterwards.
how can i know what other links/versions of my image are created?
eg. :
or maybe https://cdck-file-uploads-global.s3.dualstack.us-west-2.amazonaws.com/meta/original/>>>2<<<X/a/3/a37df25f15fccd47dc543f3d5751d81cb61dbe6b.jpeg (this one doesnt exist)
Since it’s a custom URL scheme, that kind of link will only work in a Discourse instance. Plus, if you want the link to actually work, it’ll need to be a link to an image on the same instance.
Why would you want to know? In Discourse, there are the “original” and a bunch of thumbnails (what we call optimized) which are mostly generated to support different pixel ratios.
