No, that IS the filename as it appears on the bottom 'attachment'
listing, 'Embedded' is the beginning of the filename. All 14 of them
were named like that followed by individual digits. In the email was a
blank box for each one that would normally show.
As another test I saved one of the .PNG files and then just sent myself
an email I created with that .PNG file embedded. Open the email and the
picture shows? Has to be a problem on the sender's end?
