Adding files to Yandex.Disk

Upload files for your tasks to Yandex.Disk and add them to the project:

Project instructions

To add an image to the project instructions:

• Visual editor
• HTML markup

1. Click the button on the toolbar.
2. Insert /api/proxy/<unique name of your proxy>/<name of the file you want to add> in the field that appears. For example: /api/proxy/yadisk/image1.jpg.
3. Press Enter.

1. Click the button on the toolbar.
2. Add the HTML tag <img src="/api/proxy/<unique name of your proxy>/<path to and name of the file you want to add>"> in the input field. For example: <img src="/api/proxy/yadisk/image1.jpg">.

Task interface

To add a file such as an image or an audio clip in the task interface:

1. Set the string data type for the input data field in which you will pass the file link.

2. Insert the file. Note the format that specifies the field name: proxy <field with the file link>

   • Image
   • Audio or video
   • Editor for image area selection

   Add an image in the HTML block using one of the methods:

   • Using the Picture: {{img src=(proxy image)}} component.
   • Using an HTML tag: <img src="{{proxy image}}">.

   Add the HTML tag:

   • To insert an audio recording in the player: <audio src="{{proxy audio}}" controls>;
   • To embed a video recording in the player: <video src="{{proxy video}}" controls>.

   Add the{{field type="image-annotation" name="result" src=(proxy image)}} component.
3. Include relative links to the Yandex.Disk files in the TSV file with tasks. The link format should be <unique name of your proxy>/<path to and name of the file you want to add>. For example: yadisk/image1.jpg or yadisk/photos/image1.png. Note that the folder name is not always required. Sometimes it's enough to specify the proxy name and file name separated by a slash ("/").
