I've spent all afternoon wading through the screenshots I took of the world event that took place on Thursday for the end of Closed Beta. I used Google's Picasa service to give everyone a way to view them easily. I highly recommend using the "Slideshow" button above the first image so you can see them in full screen mode.
World Event in Closed Beta
For those of you who really want to wade through random WoW images there's another album with various screenshots I took in Beta, and one with general eyecandy pics I collected over the last year and a half playing WoW. There are captions on all to explain what they are.
