AHHHH! I didn't think anyone was using this embedder feature, but there is a "save image" item in the context menu of the (big) image which gets displayed when you click the (small) image in the "taken-snapshots-viewer". Where you save it is up to you smile. The frame around the selected item is a different thing... I'll see what I can do.
