Picmv is a freeware image viewer that also features image management functions. It was specifically designed to work well with digital cameras but also works great as an image viewer with tumbnail display. It features an advanced search function which is helpful if you have a large image archive, its also able to sort the images using lots of parameters like time, color, ratio, how many times it was viewed, pixel number and more. I suggest you take a look at this beauty if you have lots of images or own a digital camera.
