Chroma key looks like a good solution at first glance. However, there appears to be a great deal of white in the pink that makes up the frame. I suspect that key will strip out this white along with the white center. Worth a try, though. Tinker with the degree of key — it may take several passes — and see if you can preserve the white/pink in the frame.
You might try masking out the white center or bring it in to Paintshop Pro or Photoshop and clean it out there.
