Is this possible?

My products are media files, and I'm using the "ProductImage" field to upload a preview mp3. It's working fine, but I want to embedd the media player on the page to play the preview rather than opening in a separate window.

I can embedd media player ok, but it doesn't play the file. I'm setting:

<param name="filename" value=" + GetFileUrl("ProductPhoto") + ">

... but the product mp3 is stored in the database as an attachment, and GetFileUrl() just goes to "/getattachment/[guid]/[page].aspx.
