Based on a spotcheck of 10 skills, the image files in the Related Skills portion of the skill page seem to have been redirected to their parent wiki page. For instance on the Guardian page, the 4 related skills all show their title twice, rather than the skill image and the title. When you click on the Aegis image link (File:Aegis.jpg) you open the Aegis page with the note: (Redirected from File:Aegis.jpg) at the top. I believe the Skills template has been modded - I have no idea on how/what to fix the redirects and get the image back.
