Release(Album) images

I see that I can get Release(album) images by track. For example...if I do this:

http://us.music.yahooapis.com/track/v1/ite...>?appid=****

I get XML formated like this:

<Tracks>
<Track>
<Artist />
<Album>
<Release>
<Image />
<Image />
<Image />
<Image />
</Release>
</Album>
<Category />
<Category />
<Category />
</Track>
</Tracks>

I want to get all tracks for a specifc release so I'm doing the following:

http://us.music.yahooapis.com/release/v1/i...response=tracks

I was also hoping to get the images for the Release(album) right in this call. However I can't seem to figure out how to do it. Maybe I can't?

I tried passing in 'images' with the response parameter...that causes an error.

Can anyone tell me if this is possible...and if so, how to make the call.
