vvvP is a program designed to catalog and handle digital images.
Digital camera owners quickly learn that it is very easy to take a lot of images: they are free, after all. What quickly becomes difficult is handling those images: after some time it is almost impossible to find a particular image.
Programs like vvvP are used to handle a large number of images, so you will be able to easily find the images that you are looking for. Then you will be able to look at the images or copy them to folder in the computer, for example to give them to a friend.
vvvP is available for Windows, Linux and for OS X (Intel only). You can exchange catalogs among Windows, Linux and OS X computers, and you can connect Windows, Linux and OS X computers to the same (Windows, Linux or OS X) server. This means that you can share the same catalog among many computers connected by a network.
