The group picture of the Debconf11 has been up for 33 hours now and finally I also had a moment of time to make the numbered version so you can add peoples names to it.
I am pleased to say it is the one of the largest Debconf group photos yet with 263 people and 86 Mpix resolution. It took 10 separate images to stitch it together (from 44 images taken) and 15 fixes of stitching bugs deemed RC, 4 bugs were noted post-release, deemed minor. Most noticeable is on very skinny leg in the front row :).
