We haven't made a tutorial for Snap yet, but we think it's pretty easy to use. The program loads all the photos in your My Pictures folder (we'll add a way to customize this very soon), and then you can organize them and apply or remove labels. Note that the first time you start Snap, it will create a cache of all your pictures to help speed up loading. This step is a little slow at this point (we're working on speeding it up). After this, startup should be much faster. If you try out Snap and you feel up to it, why not contribute a tutorial yourself? Just let us know at snap-photo-devel[at]sourceforge.net.
