Embedding Does Not Make It To Sent

[AllisonBrown]

Hi There Folks!
Just having some trouble trying to Embed videos and Soundcloud into my Roundcube emails - they appear in the compose window but when I send the messages they don't get to the recipient - the rest of the message works, just the space where the embedded stuff should be is blank.  Also if there's any way to make links turn into pictures the way it does with my Yahoo account that'd be helpful too.
Appreciate any advice!
Allison

Emails aren't as flexible as a web page, things like iframes and javascript wont work in emails meaning there isn't any way to send anything embedded other than images.
