Thumbnails of many images on Commons and English Wikipedia are appearing grainy, because the appropriately sized copies are not being generated. MediaWiki then upscales a low-res version, with hideous results. Affected images appear to mostly be large JPEGs with a portrait orientation (long Y axis). See these pages for examples: https://commons.wikimedia.org/wiki/Commons:Graphics_village_pump https://test.wikipedia.org/wiki/User:Guanaco/sandbox
