Broken images in Nitter feeds

Every feed served by this common Twitter front end platform produces broken images, e.g. the feed currently embeds an image at http://tweet.lambda.dance/pic/media%2FExwSswEXMAY7w9W.jpg but when I import the feed into NewsBlur it is replaced with https://imageproxy.newsblur.com/sc,saUrNRIFHH7zuouMouHZ61PkSer3_lKBMBQdww4t7wTk=/http:/tweet.lambda.dance/pic/media/ExwSswEXMAY7w9W.jpg which fails to load.

I was only allowed to put two links in the post; the feed I’m referring to is mediocritee / @_mediocritee
