I tried to send an email with an attached photo file. The system tried to embed the file as a photo album within the email.  My PC had performed the procedure successfully many times before.  This time, the task bar headed "Publishing photo 1 of 1" is locked (at about 50% complete) and, as a result, I am unable to send or receive emails.  I can find no method of deleting the original file which is stuck.  Please advise.
