If you ignore their instructions and do nothing, then on Dec 1, any photos still on the webshots site will be gone.
As in...POOF.
If you follow the link I posted upthread (in the post right before yours), it will take you to a page where you can elect to download all your photos - webshots/smile is providing this service.
You sign in and click on DOWNLOAD and you'll shortly (not immediately) receive a link to the .zip file(s) you can download to your home PC or laptop.
That file will only be available for two weeks.
You can request it again, but only if the photos are still on the webshots site.
Not difficult at all.
