Is there a way of permanently including "Save As" in the Preview (version 6.0.1) File menu, I have to type "Save As" in the help menu for it to temporarily appear in the File menu. "Save As" is useful for changing from a .png (ie a screen shot) to a .jpg; I just did that by rewriting the file name and when I tried to add it as an .jpg attachment I got the message "This PNG image has the incorrect file extension."!
