Upload alternate images

Associate multiple image variations that enable you to showcase a media item in any location

Each uploaded media item in your JWP account has a thumbnail image associated with it. This image is shown as a preview in the player until content playback begins.

This thumbnail image also can be used to promote the media item. However, you might need other images to increase viewer engagement and to accommodate specific platform requirements:

  • Using an image with an overlay of text
  • Showcasing a media item on a Roku device with a 9:13 aspect ratio image and on web with a 16:9 aspect ratio image

To accommodate scenarios such as these, you can upload and label multiple alternate images from the JWP dashboard.


JWP removes all sensitive metadata when an image is uploaded to protect privacy and ensure user security. Image capture tools can add sensitive metadata (known as EXIF) to images, including GPS location of the picture, time of day, and the camera used.


A custom static preview file should adhere to the following standards.

Standard Information
Accepted file formats
  • .jpg
  • .png
  • .webp
Number of active images 20 image labels maximum per property
File size limit ≀ 50 MB

Upload alternate images


If you are a developer or have developer resources, you can use the Management API to upload alternate images.

Use the following steps to upload alternate images to a media item:

  1. From your Media Library, click the name of a video. The media details page appears.
  2. In the Additional Images section, click Manage Images. The Additional Images popup window appears.
  3. Click Add an Image.
  4. Click Choose File to choose and upload a high-resolution, custom image file.


    When a request for an image is made to the JWP Delivery API, the image is dynamically resized. As a result, it is best to use high-resolution images for your alternate images.

  5. In the Create Label textbox, type a unique label for the uploaded image. This label can only contain letters, numbers, underscores, and dashes. The label is used to identify the correct image to display.
  6. Click Create Label to apply the label to the image. The label will appear in the Selected Image Label section.


    If you have existing labels associated with your account, you can click on a label name from the Available Image Label box to apply to the uploaded image.

  7. Click Save.
