OK, I admit it, I've been putting it off for months, but I've eventually gone with the flickr pro account. The normal account was fine, but it meant that I had to time when I wanted to upload files online, sometimes, leaving no room at the end of the month (monthly upload of 20Mb) if I wanted to share some newer files. The pro account gives you something like 2Gb upload a month, and also allows you to create more than 3 "sets". It works out to be something poor like $2 a month to keep photos online, which personally, its the first time I've paid for an online service (no jokes please!!) and more than happy.
Anyhooo, my flickr account is : http://www.flickr.com/photos/docwharton/
