Re: Cloud collaboration for photo archive
If you dont want to share your Gdrive or drobbox you can create a new Gmail together and use that to make a new dropbox account or use Gdrive. You can also use alternatives to these solutions. I have only ever used GDrive as online storage, so i don't have experience with any of these, but here is a link to a list of alternatives.
