Up until now I've been using a little windows program called "Windows Photo Info" to keyword my images. It allows batch operations so if a bunch of pics happen to use "3d" as a word I can do a mass-operation of attaching "3d, render, graphic" to them all. It also allows descriptions and titles.
Problem: Vista does not seem to use this.
Does anyone know some good software (preferably free) for this purpose that is compatible with Vista?
