Where are Skyrim Screenshots saved?
Solution 1:
Should be Program Files(x86)/Steam/SteamApps/Common/Skyrim
Solution 2:
Right-click on the game in the Steam list, and click "View Screenshots". Then, click "Show on Disk" to open the directory where your screenshots are held:
C:\Program Files (x86)\Steam\userdata\<some_id>\760\remote\72850\screenshots
Solution 3:
In case you have Skyrim installed via the disk the screenshots are stored in the root of your Skyrim installation directory, something like C:\Program Files (x86)\Skyrim.
