I think I need more context. Is this what you're
saying?
- we want to use less storage space
- images we are generating and caching for not-Wikipedia should be the
first to go
- we assume weird sizes are from not-Wikipedia. So let's cache them for
less time
- except, that doesn't work, because of tall images
- so maybe we should change the image request format?
Lovely summary.
Given Filippo's focus on keeping things simple (hurray!), why not
something more straightforward, like: purge everything non-common, the
tall images' thumbs will just need to be regenerated. Needs some
calculation of the drawbacks but better than altering MediaWiki.
