Oh at last i had enough time to finish Drak'Tharon Keep, Gundrak and Ahn'kahet: The Old Kingdom. On "Full View" you will see them on 600px wide but if you really want to see the full size picture press "Download" button. Then they will be on their full resolution which is 1280x1024. The full view is set to 600px wide because the screenshots are not HD captured theirselves, and the full view looks worse than the smaller view.
Enjoy :}
