@mattches Any further ideas about this?
I’ve tested and confirmed that I can send an email with the same content at two different times with two different results:
Whether or not images in the email (whether as screenshots or ‘Copy image’ images) will be replaced with thumbnails is unpredictable. I’ve so far found no ‘pattern’ to its happening or ‘not happening.’ Nor have I found any way of forcing the result (either way) to be duplicated.
Even when the conversion to thumbnails does occur, I can reconstruct the same email, send it again, and this time, in all likelihood, the images will come through normally.
Thanks.
(Also, my two previous posts here somehow got doubled – i.e., two copies of each in the replies. I didn’t post them twice.)
