Finally I took my time and uploaded all my good Debconf7 photos to Flickr, 193 photos in total. Most interestingly I have created a much improved version of the group photo.
Please do note that these photos are under Creative Commons Attribution licence, so please do give credit where it is due. And I also would love if you would send me an email telling where you have used my photos of the event.
Links to other photos (and mugshots) can be found via the corresponding wiki page.
