[Evolution] email body format

[jd <jd1008 gmail com>]

I have config'ed evo to use html as message format.

When I copy html content from some web page and 
paste it into a new message, none of the images
are displayed. I only see what appears like place
holders for what should be the image. Sometimes
I do not even see that!
Is there a way to force evo to display the image
in the message before I send it, so I can be sure
of the content?
