The MLP wiki uses a custom JS script. I am not sure about the "other wikis" since you haven't mentioned them by name. I know a more common script is LinkPreview. However, I believe this script includes part of the article text. I am not sure if there is a setting to show just the image. - Edit:

Also, when did you have your wiki's domain changed? It seems the new domain has not yet been registered with InterwikiDispatcher.
