Aperture Email Attachments are Embedded in the Email Sent to Windows PC's
I've searched the forum and have run across this problem discussed previously. When sharing photos from Aperture 3.4.3 using the Email preset, the jpg's show up embedded in the body of the email when sent to people using PC's and running Outlook. Oftentimes, the jpgs actually appear as thumbnails as well, and not full size. I've tried the suggestions found here in this forum without any success. In Mail, I have "windows friendly attachments" checked, although that particular menu item is greyed out, and can't either be selected or de-selected. I've also formatted the email as "Plain Text". Still photos attached don't show up on the Windows PC's as attachments. I even exported a photo from Aperture to my desktop, then attached that jpg to an email, and got the same results. I'm not sure if this is an Aperture problem, or a Mail problem. I'm using Aperture 3.4.3 and OS 10.7 . Am I missing something? Thanks in advance.
