what's the difference between this rake task that's deleting images one by one and just doing a rm -rf preview_cards ?
@squirrel rm -rf preview_cards is much faster and doesn't spam stdout.
@noelle can i ^C this rake task and do that
@squirrel Probably? I ^Ced on elekk and just ignored it, and everything's working fine.
@squirrel my best guess is it's purging it from the db as well?
not sure.
