maybe I'm worrying too much? Does the next link mean each album can be uploaded as an entirety?

How do I download all the files I've uploaded to My Opera? The files export will create a .zip archive of any files listed in your account's 'Files overview', as well as images in your albums. Your images can then be uploaded to Flickr, Google+, Photobucket, Fotki, or other photo sharing sites.

When I clicked on the link to Google+ I was directed to my own gmail sign on page - so I didn't get any useful info (how strange, how very google+)

The Fotki link is to a useless (to me) site

Clicking on the Flickr link does not offer any help, just sign up.

but clicking on the photobucket link gets this -

Uploading With Photobucket ... Bulk Upload - The Photobucket Backup, for Windows and Mac. An awesome piece of software that will allow you to automatically back-up images saved on your computer ... Google Chrome users can also upload whole folders of images
