Rainy Day Photoshop Action
PanosFX is the creator of some of the best Photoshop actions available. I have posted about some of his actions before and his site is definitely one to watch out for if you are a fun of photoshop actions. Rainy Day is another great action by Panos that works with Photoshop CS and CS2 and will give your images an effect and look as if they are seen through the window while it rains.
