Hi, I'm an admin for the Russian 7kingdoms.ru wiki. We've been cleaning out some images with questionable license status, and some of them were taken from AWOIAF.
Runestone_by_krassenka.jpg is a 3D digital art called Citadel by John Bliss. It has nothing to do with Runestone or A Song of Ice and Fire. Apparently, somebody named Krassy put a gallery of fantasy castles on their blog back in 2012, with cropped out watermarks and made-up captions, and that's it. You should probably check any other images uploaded by the user Igra prestola.
By the way, Lanna_by_Liquoricey.png is a slightly photoshopped stock image.
