In WoW, if you hit Printscreen on the keyboard, a .TGA file will be created in your warcraft/screenshots folder.  You'll probably need a program to convert the pictures to something you can use.  I recommend XnView (http://perso.orange.fr/pierre.g/xnview/endownload.html).  It's free and it's cool.

Anyway, here's some shots I've taken recently.  Please share your own!

Oh, and to be web friendly, please resize your pics (again, you can do this with XnView)

I call this one 'Deep Trouble'

I call this one "Don't Turn Around".  Not quite as impressive as Hawkeye's.... but still kinda funny.

At the top of Ironforge's mountain is a flag.  I went up there, but nothing cool to see.  This was the best screenshot on the way up.  Oh, I also got to the planes and runways.  Nothing there to do.  

This is the dam in Loch Modan, but viewed from the wetlands.

FYI, when I see cool pix in this thread, I'll add them to the screenshot-of-the-day in the web front end.

Some recent shots:
1) Big Blue Dragon and a Giant in the distance.  Both dwarf my dwarf.
2,3) Thought the wetlands looked particularly striking at sunset
4) Went thru the dark portal to the Outlands and finally acquired a flying mount.  This is a neat looking forest I flew thru.

Just a couple pix from exploring tonight.  Yes, that Mammoth only comes up to the giant's ankle.
