I prefer to store new image sizes (like in ZPhoto and Photo) and only process once for every new image.
The problem I have with that is the potential data.fs bloat. But if you did it only on upload, that would be a solution...
I think that Marc's ImageTag hotfix and Photo/ZPhoto products might need to be merged in the standard image object: A standard image may or not contain its own other resized versions, as a user's choice, AND a standard image's tag methods should be able to custom-resize it on the fly, using PIL (in the medium term I expect PIL to workout its quality issues).
What does the list think about this? :)
Problem I have with that is, if you don't care about the dynamic resizing, then why muck with PIL? THat's why, I think it's good to make it a 'monkey patch' that can either be installed or not... So perhaps your 'uber-image' package could allow features to be enabled or disabled - so if you don't have PIL installed, it doesn't cause an error if it's disabled.
