Hover form to display media object image


Have a need to create an E1 hover form to displace an image that's loaded in media object. Hover form does not have media object control. Create a text block with html image tag to media attachment image that is located on a network share (file:///\\networkshare\location). However this only work in IE because UNC path does not work with chrome/firefox. The media object control will copy the image to a temp location on the web server. Wondering if there is an API/solution that will do the same.
