With Outlook Express, you could attach photos so it was simple to simply scroll down. You could click on the attachment to make them bigger if you needed to but often it wasn't necessary.
Live Mail seems to have a choice of arty formats, squared off (who wants to show their pictured clumsily cropped?)or at arty overlapping angles...
I can't see any way of just sending reasonable sized photos that you can look through without going to some boring time-consuming  palaver of film shows or squares or whatever some too-clever IT <Removed for CoC violation> has thought up to torture people with.
But maybe I have missed something...if I have PLEASE let me know.
Many thanks.
