"Simple and easy"
A trained monkey could use it
Good interface and a very easy to use
From what I've seen, just seems to copy and paste into a system folder. Nothing spectacular.
Although it does seem to only perform a very basic task, most users should not be mucking around in the system folder anyway. This program safely copies the image to the system folder and is easier and quicker then doing to manually anyway.
