	;; Using javax.imageio and funcool/cats
	;; it's leaking fds, take care!
	(defn valid-jpg-image? [image-url]
	(let [image-input (-> image-url io/input-stream ImageIO/createImageInputStream)
	encoders (-> (ImageIO/getImageReadersByFormatName "jpg") iterator-seq)
	image-result (map #(either/try-either (doto % (.setInput image-input) (.read 0))) encoders)]
	(->> image-result either/rights not-empty boolean)))
