I thought I've been able to do this since the 2017 upgrade, but can't do it now. No matter what I add - snipped and pasted screenshot, or a pic copied from the web, I add it to my email and it looks fine in Compose mode - but after sending it to myself and checking the Sent item (or the received item) the embedded item isn't there. I tried many choices under Settings and came up empty. I'm working in Xfinity Connect (don't know if it's Lite or not, don't know how to tell) and using Chrome browser on Windows 10. Thanks.
I just tried it with two different images in two different emails, and the images appeared in both the sent and received emails. I'm using Windows 10 with Firefox 58.
Thanks rf - well I'll be. I tried it in IE and it worked fine - but tried again in Chrome and still nothing. Can't imagine my Xfinity Connect Settings are different browsers, so it looks like this is a comcast/Chrome incompatibilty. Who's a thunk it. I really don't like IE, but knowing I have an alternative (if I remember it next time I need it) is good. Thanks!
