Comment (by kraftbj):

 Pitfalls of Viper007's Regen Thumbnails plugin (I think the most popular
 way to do this currently). Image regen is a stressful process for a
 server. His plugin requires the browser window open as it reloads the page
 to continue along the path to prevent PHP timeouts.

 In regenerating thumbnails on sites with a ~10 GB of original images, it
 can take a very long amount of time on a typical shared hosting
 environment.

 Any solution would need to be able to happen in the background, be hard
 enough to trigger to not kill a server—possibly having some type of record
 of what images already have what image sizes to reduce work only to add
 new sizes.
