Thumbnail of swf added with embed video module

Hi guys. I have installed the embed video module, and I've added a swf file (panoramic of church in which a friend of mine was recently married) and I want to have a thumbnail generated for the swf. Any ideas how?

And secondly I suppose: When viewing the image, can the thumbnail be removed? See link: http://www.doceave.com/gallery2/main.php?g2_itemId=15952
(the bottom video-generic-thumbnail I want removed)

Perhaps someone could tell me where to delete a line to achieve the second request?

Thanks
