Thanks, Kirk, however, I must report disappointment again. I tried the review option and after that failed added the separate email for each photo (even though I was only sending one).
I see the email in the Outbox. I can open it, edit it, open the image. But it won't actually make it out of my Outlook into the world and, interestingly, won't save a copy in the Drafts folder.
The message "None of your e-mail accounts could send to this recipient" seems to point to an inability of PM's email facility to handshake with Outlook. I can use Outlook to send images from Nikon ViewNX2, a program whose deficiencies caused me to buy PM.
Is this a MAPI vs. POP thing? I only use POP for my email.
