Comment (by FolioVision):

 Hi Guys,

 What about simply generating the missing image sizes on save (assuming
 those sizes are going into content)? There's a nice hook for on save. This
 would work for the original poster's issue.

 If an entire theme's thumbnail image sizes are changed, perhaps there
 should be a large button to regenerate images throughout the website. When
 a user has to push a button to get an action, consequences are on the
 users shoulders (especially if we warn them with a javascript warning and
 confirm button). For regeneration, we should probably pace it by default
 so it does not use all of a server's resources.
