         writeln(images); // ["public/images/testprog.jpg"]
         res.render!("index.dt",images);
     }
  }

When you get the 404, do you see the contents of 'writeln(images);' in your terminal?

yes. the 404 is only for the image the page still renders fine, but the image is replaced by the missing image image.

You need to make the images accessible over HTTP. Note the use of staticFileServer in the following example: http://vibed.org/docs#http-routing
