Caching is up to the browser, so it's a per-user thing:
The image proxy isn't a caching proxy. Proxied images are never saved to disk, and only small chunks of images are stored in memory at any one time. The proxy does work with client-side caching (it passes on appropriate cache-related headers, etc.), so you may cache images.
Also in that post:
Increasing fault-tolerance is a long-term goal, but (re)creating a truly decentralized and uncensorable forum is outside of bitcointalk.org's scope.
Now I don't really believe theymos was specifically talking about the image proxy or images here, but..
Should the preservation of posted images be part of the fault-tolerance goals of the forum? Does the removal of an image present a fault in the context of a thread/post?
As an example, let's look at the reference thread of a flag theymos created.
Without the images, as it stands now, does the flag still hold water?? or.. at least as much as it does with images?
