 Replying to [comment:3 scribu]:
 > Here's one scenario where having intermediate image sizes generated "on
 the fly" would be bad:
 >
 > Say you have a moderately busy homepage (tens of hits per second), where
 you display a 'medium' image for each recent post. You upload a large
 image for a post and publish the post.
 >
 > The first user hits the home page; the 'medium' image for the new post
 isn't there, so WP sets out to generate it.
 >
 > Assuming it takes 2-3 seconds to do that, there will already be tens of
 other WP instances trying to generate the same image.
 >
 > Server runs out of memory and starts refusing connections or just dies.

 Good catch! I will try to find a solution...
