Original Title: Forwarding emails with pictures that turn out as a slide show

I have Windows 7 and use windows live mail 2012. From time to time I receive emails with pictures in the body of the email and more often than not a caption at the side of the picture or underneath the picture. If I try to forward it on the pictures end up as a slide show across the top of the email with the body of the email showing square boxes where the picture should be. Sorry this is not very technical but its the best way I can describe it.  I have had the trouble in the past but not for a long time now. This latest problem started with a friend who has just bought a new computer and has Windows 8. Could it be that now 8 and 7 are not compatible? My ISP is Sky.

Does any one know the answer to this problem. It doesn't happen all the time just from time to time but its annoying when it does happen.
