Hopefully you have now setup a Flickr account by now, if you have a Yahoo! account, you basically just have to sign into your Yahoo! account to create a Flickr one. Its worth noting that you don’t need a Pro account to use Flickr and it is completely free.
However Flickr can be quite difficult to figure out how to add people as a contact, first you have to go to my profile page (this was linked in the Welcome post, but is also linked here).
Then you click on the “add to contacts” button, which is shown in the following screenshot circled in red:
After clicking on this you are then taken to the following screen:
Where you can mark me as a friend/family as appropriate.
At this stage I am sent an email where I can add you as a friend/family member, once I have done this you can view pictures that I have marked as such.
