publishing - Software recommendations for magazine layout?

I use Word now but I would like to find a better software for laying out a magazine.

In this magazine, I would like to create columns (2 or 3 depending on the page), insert image on 1, 2 or 3 columns (like in a newspaper), independent frames on 1, 2 or 3 columns with text inside, a header and a footer different for the left or right page, etc.

Answer

Adobe InDesign or QuarkXPress. These are desktop publishing programs, which are designed to do exactly what you want to do (among many other things): lay out printed pieces like a magazine.
