Often, people are looking to build an element collection, and come here for help.  I'm usually pretty jaded, because I don't really think its worthwhile, safe, or even very interesting in the long run.  However, the process has a long tenure on deze thar intarwebs, as seen from the Wikipedia page: http://en.wikipedia.org/wiki/Element_collecting  So I'd like to know, who's seen the most extensive element collection, online, with images.

I have an element collection, but I don't try that hard to add more to it, only isloating them or buying them if I need them for a specific reaction. At the moment I have only 28 out of the 91 I might eventually get.
Woelen, a member here, and admin at sciencemadness has most of themhttp://woelen.homescience.net/science/chem/compounds/index2.html Just click on one there to see a picture.
I made a thread of pictures on scimad, and there are quite a few people who have good sized collections:http://www.sciencemadness.org/talk/viewthread.php?tid=29040

An ex-mod here, jdurg, had most (if not all) of these 91. I think pictures of his elements were used in some book, but I don't remember details. Perhaps browsing his posts will yield some more information.

I was also wondering is there was any science museum or "learn-a-torium" for kids that might have a periodic table display, with purified samples and/or ores setup.  Of course, Woelen:'s page does the gasses right -- no point in showing tubes that might as well contain air, but instead send a current through and show all the colors possible.  But someone, with adequate shielding, should show us what we can get with a radon lamp, as an example.
