Node server doesn't load external resources

Yesterday I tried to use a little node.js script as localhost in my website development workflow.

It works fine but no external resources are shown - my browser gives me the following error message: "XMLHttpRequest cannot loadhttp://xxx.xxx/xxx/wallpaper_01.jpg. Origin http://localhost:3000 is not allowed by Access-Control-Allow-Origin."

I don't know node.js at all. How do I have to change the script to get it work?

var connect = require('connect');
var serveStatic = require('serve-static');
var app = connect();


app.use(serveStatic("./_distribution"));
app.listen(3000);



Thanks a lot

Your question is not about node; it's about how web browsers and web servers work. Please read:
