http://signavatar.com/15890_s.gif First: You've got a picture in there that's 800x286 pixels. The maximum signature size is 700x250.
Second: Your other picture in the rotation fills the full 700x250 boundaries by itself.
With an image that big, you can't fit any text below it. Please fix this.

UPDATE: I've edited the first post to include the link to a relatively low quality download. I made it primarily for my mobile phone, but I see no reason not to share it.
