I am looking for insturctions with picture on how to make a wedding cake with roses between each tier. Help

Real roses or icing ones?

Use the hidden pillars. This will give you about 2" between the tiers. You can then lay the roses in this 2" space.

Here's a pic of one I did with fall flowers, and a link to my Flickr site with some "under construction pics": http://forum.cakecentral.com/modules.php?name=gallery&file=displayimage&pid=1119353 / http://www.flickr.com/photos/55969028@N00/page10/
