image from url ?

[fabulousduck]

is it possible in any way to give the image() function an url to an image from cloudinary or another such service ?

or would i have to download the image from cloudinary. pass it in. and delete it locally again?

var http = require("http");
var images = require("images");

var url = 'http://www.lenna.org/full/l_hires.jpg';

http.get(url, function(res) {
    var buffer = [];
    var currentByte = 0;
    var countByte = res.headers['content-length'];
    if (res.statusCode === 200) {
        res.on("data", function(trunk) {
            buffer.push(trunk);
            currentByte += trunk.length;
            console.log(Math.floor(currentByte / countByte * 100) + "% " + currentByte + "/" + countByte);
        });
        res.on("end", function() {
            var data = Buffer.concat(buffer);
            var full = images(data).resize(512);
            var harf = images(full, 0, 0, 512, 512);
            harf.save("Lenna.jpg");
            console.log("Done!");
            // WARNING this picture contains nudity.
        });
    }
});
