Спецификации:

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

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

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

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

Блок HTML:

{{img src=image width="100%" height="400px"}}
<div>Есть ли на картинке <b>дорожный знак</b>?<div>
<div> {{field type="radio" name="result" value="OK" label="Да" hotkey="1"}}
{{field type="radio" name="result" value="BAD" label="Нет" hotkey="2"}}
{{field type="radio" name="result" value="404" label="Ошибка загрузки" hotkey="3"}}</div>

Блок 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)
    }
});

function extend(ParentClass, constructorFunction, prototypeHash) {
    constructorFunction = constructorFunction || function() {};
    prototypeHash = prototypeHash || {};
    if (ParentClass) {
        constructorFunction.prototype = Object.create(ParentClass.prototype);
    }
    for (var i in prototypeHash) {

Блок HTML:

{{field type="image-annotation" name="result" src=image}}

Блок JavaScript:

1. Подключите библиотеку $TOLOKA_ASSETS/js/image-annotation.js (нажмите в блоке Интерфейс задания на странице проекта).

2. 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)
     }
   });

       constructorFunction.prototype = Object.create(ParentClass.prototype);
     }
     for (var i in prototypeHash) {
       constructorFunction.prototype[i] = prototypeHash[i];
     }
     return constructorFunction;
   }
