# Media Preview

The Media Preview widget can be used to display image, audio, video, and document media, given a supported media source. Currently supported media sources include media URLs, attachment properties, and media reference properties.

## Configuration Options

* Media string
  * Media string options support images referenced in the following three formats to render a preview of the media:
    * Blobster RID, for example, `ri.blobster.main.image.ab1c23d4-56ef-789g-h012-3456ij78k90l`.
    * Media URL
      * If referencing a media URL from a media set, the URL should be of the format: `https://{my-foundry-url}/mio/api/media-set/{media set rid}/items/{media item rid}`.
      * If referencing a media URL from a dataset, the URL should be of the format: `https://{my-foundry-url}/foundry-data-proxy/api/web/dataproxy/datasets/{dataset rid}/transactions/{transaction rid}/{filename}` or `https://{my-foundry-url}/foundry-data-proxy/api/web/dataproxy/datasets/{dataset rid}/views/{branch name}/{filename}`.
      * If referencing an external media URL, ensure access has been configured in your enrollment’s [Content Security Policy](../../administration/embed-foundry-externally/index.md) settings.
    * Data URL with a Base64-encoded media, for example, `data:image/png;base64,{base64-encoded image}`.
* Attachment property
  * Define an object set with a single object and select the attachment typed property to render a preview of the media for that object.
* Media reference property
  * Define an object set with a single object and select the [media reference](../../media-sets-advanced-formats/media-overview/index.md#media-references) typed property to render a preview of the media for that object.

## Limitations

* The Media Preview widget does not support viewing attachments embedded within a PDF file. To access embedded files within a PDF, download the PDF and open it in a local PDF viewer application.
