Regenerating thumbnails

Jan 10, 2009 at 4:10 PM
Hello. Sometimes I forget to rotate pics before copying them to the target directory. In this case the thumbnails are created sideways. How would I go about forcing a regeneration of the thumbnails? I'm writing them to disk. I've looked for the Temp directory that is described as housing the thumbnails, but can't find it.

Thanks for any help.
