Hi Stephen

my evidence seems to show that it may be random?!  The smaller  
attachment was embedded & icon, the larger was icon only (see below) -  
I would have thought it would be the other way around.  There have  
been other times when I have sent multiple attachmentts where some  
were embedded & some were icons/both.

Cheers,  Alex
