[SOLVED] Spliting post in two vertical columns?

I would like to split my posts in two vertical columns, so that my text in the posts are read like a newspaper with narrow columns, instead of one wide column. Is there a way to do this? And is there a way to create a template that I can use for all my posts that will allow the right column to contain nothing but an image?

This is how it looks now:
