A little bird just informed me of a Mathematica solution to this question (the underlying implementation still uses JLink, but this answer hides all the java related code): imgur[expr_] := Module[ {url, key, image, data, xml, imgurUrl}, url = “http://api.imgur.com/2/upload”; key = “c07bc3fb59ef878d5e23a0c4972fbb29”; image = Fold[ExportString, expr, {“PNG”, “Base64”}]; xml = Import[url, “XML”, “RequestMethod” -> … Read more
