"description":"When this is enabled, MediaViewer will try to guess image URLs instead of making an imageinfo API to get them from the server. This speeds up image loading, but will result in 404s when $wgGenerateThumbnailOnParse (so the thumbnails are only generated as a result of the API request). MediaViewer will catch such 404 errors and fall back to the API request, but depending on how the site is set up, the 404 might get cached, or redirected, causing the image load to fail. The safe way to use URL guessing is with a 404 handler: https://www.mediawiki.org/wiki/Manual:Thumb.php#404_Handler",
