We’re thinking of changing our setting for max image size kb, as we we started out with it quite high and need to save some S3 costs. I wanted to check my understanding before hitting the button.

I think this setting on setting only gets applied to new uploads? Is there a way to resize existing uploads to use the new max value (e.g. resize the originals of anything over the max)? I’m was sort of hoping something like `bundle exec rake posts:rebake` would do it (maybe)?

If that wouldn’t work, what’s the best approach here? An older build of discourse had a Rails [script/downsize\_uploads.rb](https://github.com/discourse/discourse/blob/4c89f7f88165c28bfc8ecb15a3be7346985d384e/script/downsize_uploads.rb) but I think that’s gone from github now? Is there anything else or is my best bet just to use that code on a more recent Discourse - I think it uses megapixel as the constraint rather than kb?

Thanks for any help/advice.
