If you look at the source of the avatar image, for all the actual pictures and question marks it appears to be something of the form:
http://213.155.73.107/Client/pics/spieler/50680.jpg(that's reikja's ... the question marks seem to "resolve to" 0.jpg )
The ones that show up as Xs are of the form:
http://62.138.43.168/Client/pics/spieler/35448.jpgThere are pics on 62.138.43.168, and I was able to find a forum post that displayed one. I suspect this means that server just has not been set up to automatically resolve non-existant #ers to a default pic (such as 0.jpg), so all the people showing Xs are people "assigned" to 62.138.43.168 who have not submitted avatar pics.
The directory on 213.155.73.107 was not viewable, so I wasn't able to even try to discern any sort of pattern of what user# is assigned to which server, but it at least wasn't obvious from the few I saw (except that all the ones on 62.138... were added in 2003, so maybe the ones on the 213 server are more recent).
The pics (including source) are the same as those that appear in the "Spieler Info" at:
http://www.brettspielwelt.de/HallOfFame/SpielerInfo/and, I presume, in the info box within the client.
A German speaker might be able to find more definitive and/or up to date info on how to get an avatar pic added, all I could find was this unofficial bit on TheBoomer's site:
http://www.brettspielwelt.info/faqmisc.htmlI would suggest waiting for confirmation before emailing any pics off so as not to inundate or irritate anyone in case Theboomer's info is obsolete.
Does anyone else feel like taking on the task of "informing BSW" about the different behavior of the two source servers? If anyone is confident where it should be reported, I'm willing to do so since I think I understand it pretty well. Communications may prove more convenient and effective coming from someone with better command of German though.
