Project 1. Does the image contain a certain object?

Specifications:

Input:

Output:

 
{
  "image": {
  "type": "url",
  "hidden": false,
  "required": true

   "type": "string",
   "hidden": false,
   "required": true
   }
}

HTML:

{{img src=image width="100%" height="400px"}} <div>Is there a  <b>traffic sign</b> in the picture?<div>
<div> {{field type="radio" name="result" value="OK" label="Yes" hotkey="1"}}
{{field type="radio" name="result" value="BAD" label="No" hotkey="2"}}
{{field type="radio" name="result" value="404" label="Loading error" hotkey="3"}}</div>

JavaScript:

exports.Task = extend(TolokaHandlebarsTask, function(options) {
    TolokaHandlebarsTask.call(this, options);
}, {
    onRender: function() {
        // DOM element for task is formed (available via #getDOMElement())
    },
    onDestroy: function() {
        // Task is completed. Global resources can be released (if used)
    }
});
