Every sample I've seen for updating the historyitem in a Windows Phone 8 Media Hub app shows using a local image/uri for displaying the background of the item.

However, I am streaming the file, and I have a remote URI for that song cover, but I cannot seem to use this uri for the history item.

I attempted to download the image to localstorage, but this appears to not always work, and crashes the background agent.

not to mention the fact that I have to do this asynchronously, and needs to support downloading it from the background agent in case the user is not running the app when the track changes...

am I attempting to do something that isn't supported?

役に立ちましたか?

No what you are attempting is supported. It is possible to download images in background agents and then use them for the history items.
