You get your FLICKR account, oh you've done this already, sorry.

Don't forget to put a nice fat block of photos (top right of your page) using Share Photos option.

Point this to your FLICKR and it will create a pretty nice link to your Flickr Photostream. Useless, you might think, as there are no backlinks possible on that page - not quite, I say as this Flickr page creates a straightforward gateway to all your recent photos. I assume you did not forget to stuff all the descriptions with backlinks to your main site, didn't you? If you did, go on and do it!

NB! Do not use Yahoo's own PhotoSharing - it is absolutely useless as you can not put up any links there!
