Pieter Kroonenberg (shown in photo) has taken wonderful photos at IMPS 2015 and published them here (password: imps2015). The group photo, sponsored by Mplus, can be downloaded here. See also this page for photos from recent annual meetings.
The website taskforce has created pages with photos of past meetings (1980, 1995, 2001, 2003-2015) - see hyperlinks on this page. We would be grateful to receive further photos, especially for meetings for which we do not yet have pages. If you have photos to contribute, please email email@example.com.
