Jim, Modern email readers tend to be quite smart these days. Many of them now scan the email for linked/attached content and show previews. This is entirely a function of the email reader and not the way the email is composed. It may be the case that some photo-sharing sites assist in giving these previews such that not just any included URL to an image will result in a proper preview. I think I've noticed that links to my own web domain where I have uploaded images do not show previews - but people linked in flickr do have previews... -|<ipp
