I see the red-X. Using IE. Never have figured out which setting would fix this, or should I say, never have spent the time to look for the answer. Hope someone else knows!!
I actually had this happen to me earlier today (in a different way) when trying to paste a small Excel table into an Outlook email, that uses Word. I did a paste special as a bitmap and could view it just fine, but printing the Sent email resulted in an empty box with a red-X.
Normally I block Third Party Cookies but my son must have enabled them (just checked) so that's not the problem.
As I mentioned above I can see it now but the animation is not working.
