EzyPic is designed to be FAST to use. If you have thousands of images, you will appreciate the simple and intuitive user interface.
Work through a folder of images quickly assigning them to groups and automatically being presented with the next image for assignment. Run a slideslow to preview all the images you are organizing and setup up custom categories for them.
Or use the slideslow to quickly review your choices before copying the assigned images to separate folders. Move quickly through thousands of images and select just the ones you need.
