UNCOY  Absolutely brilliant for capturing an image of a full webpage.

I've tried them all and Netfixer is both the simplest and the best.

It works all the time.

Oh, and it's free.

ZWILLIAMS  Does the same thing as Paparazzi. Except Paparazzi puts all the options up front.

YNOT  Nice utility, but needs a few features to be effective, at least for me.

Needs to remember download location. A home directory with a bunch of webshots can get to be a mess.

Also needs to have a delay timer, so that locations with dynamic or changing content have a chance to display.

Interface is small and app size is very small, making this a very useful utility with a lot of potential.

FOTO555  Works great...and at a great price (free)!
